The Chemical Abstracts System (CAS) produces a set of various databases ranging from bibliographic to chemical structure and reaction databases. All the databases originate from the printed media of Chemical Abstracts, which was first published in 1907 and is divided into different topics. Author index, general index, chemical structure index, formula index, and index guide arc entries to the corresponding database (Table 5-3). 

Ruthless adherence to full systematic nomenclature throughout these volumes would serve little useful purpose. While it is necessary for the Chemical Abstracts indexes to avoid colloquial forms, most of our contributors seem to agree that insistence on the use of, e.g. 4(17f)-pyridinone at every point, rather than the traditional but less precise 4-pyridone , produces a pedantic effect on the English style. So old-fashioned forms like pyridone coexist here with systematic names, the choice being dictated by the individual authors of the chapters. 

It should be stated that the nomenclature of the triazine derivatives is not uniform, e.g., in Chemical Abstracts the compounds are often indexed according to another sy.stem than that used in the original papers, and an additional system could have been used for this review. To avoid further complications, the author will u.se the commonest nomeclature in accordance with the representative monographs in this field (see references 12 and 45.)... 

According to the triazine nomenclature, 5-azauracil is 2,4-dioxo-l,2,3,4-tetrahydro-l,3,5-triazine (2). The subject index of Chemical Abstracts prefers s-triazine-2,4(lH,3H)-dione. Furthermore, some authors use a name derived from the lactim structure, 2,4-dihydroxy-s-triazine (3). The numbering of the substituents is the same for all these types of nomenclature. 

This review includes most of the published articles from the defined area and excludes only imidazoquinolines, which were reviewed in Weissberger-Taylor s series The Chemistry of Heterocyclic Compounds (81MI1). Comprehensive Heterocyclic Chemistry II (96MI1) mentioned only some of the azoloquinolines in the first edition the authors omitted citations about this type of compounds. The trend toward interest in these compounds can be illustrated by the number of citations in Chemical Abstract as shown in Table I. Besides Chemical Abstracts Substance/Subject (Collective) Indexes, the MDL database search has been used. 

Further steps toward universality are taken by the replacement of element and compound names wherever possible by symbols and formulas, and by adding to data in older units their recalculated SI equivalents. The usefulness of the reference sections has been increased by giving journal-title abbreviations according to the Chemical Abstracts Service Source Index, by listing in each reference all of its authors and by accompanying references to patents and journals that may be difficult to access by their Chemical... 

The Subject Index for this as well as for the preceding volume has been prepared by Dr. L. T. Capell, long associated with Chemical Abstracts and an internationally recognized authority on organic nomenclature. 

In 1928, A. M. Patterson, later one of the authors of the Ring Index, wrote Any attempt to construct a strictly logical system of names for the large number of parent ring systems now known seems impractical, at least as far as common use is concerned. 7 This sentiment is no less applicable today. For heterocycles in particular, the number of trivial names in current use is large. In the 1969 IUPAC Rules,6 63 trivially named heterocyclic skeletons with various degrees of unsaturation are listed, with a further 25 in the 1973 Tentative Rules (Section D).8 Chemical Abstracts nomenclature rules list 83 such skeletons with maximum unsaturation, many of which are not included by IUPAC. Thus, although systematic operations are often required to derive the name of a heterocyclic skeleton, the parent names to which these operations are applied are frequently trivial. 

As already pointed out, the nomenclature rules employed by Chemical Abstracts yield a unique index name for every structure, whereas the IUPAC Rules allow some latitude. This latitude is considerable with regard to the naming of substituted structures, and it is usually possible for an author to find in the rules a procedure suitable for any specific purpose. 

Because the electrochemistry of pyridines has not been reviewed before with regard to industrially significant processes, this review will therefore cover the period 1801-1983. Citations from 1801-1975 have been compiled in Swann s bibliography.1 These citation listings were broken down into six indices author, patent, product molecular formula, synonym, product name, and product type. A computer-aided search of Chemical Abstracts and the World Patent Index covered the period 1967-1983. Other sources such as the reviews on heterocyclic electrochemistry by Lund2 and Nelson3 contained useful citations. Nelson s review has a valuable table that summarizes the synthetic work by indexing the parent heterocycle.

This appendix lists the Chemical Abstracts Service Source Index, or CASSI, abbreviations for more than 1000 of the most commonly cited journals. Note that some journals of the same name are published in more than one city. Authors should check the journal name carefully and include the city to prevent misunderstanding. 

Chemical Abstracts, published semimonthly by the American Chemical Society, can be used for comprehensive literature surveys on chemical processes and operations. This publication presents a brief outline and the original reference of the published articles dealing with chemistry and related fields. Yearly and decennial indexes of subjects and authors permit location of articles concerning specific topics. 

The nomenclature of compounds listed in this index follows the usage of the authors of the chapters and not necessarily the strict lUPAC or Chemical Abstracts style. However, when a chemical name as used by the authors is widely divergent from accepted usage, the more appropriate name has been marked with an asterisk to alert the user that the index entry may not appear in the text on the page indicated. To keep entries brief, "obvious" details, such as indicated hydrogen in its usual or only possible place, have been omitted. 

Chemical Abstracts (CA) consists of two main parts, abstracts of every paper containing new chemical information, and indexes which provide access to the abstracts and thence to the original literature. It is published weekly and each issue contains a keyword index and an author index. The weekly issues are collected in volumes covering a six month period (one year, prior to 1962) and each volume contains author, chemical substance, formula, general subject, patent, and ring system indexes. Every five years (ten years, prior to 1957) the indexes for the ten volumes are combined to give Collective Indexes. These indexes are the single most important and comprehensive information tool available to the chemist...

A word of caution should be added with respect to Chemical Abstracts, as far as chirality assignments of homoannular substituted ferrocene derivatives are concerned. Until the 8th collective index, only (-f) and (—) are found as chirality indicators. For quite a long time, no descriptors were given at all, only the remark stereoisomer , followed by the registry number, which does not allow identification of a compound easily. This fact is in sharp contrast to the claims of Chemical Abstracts Service authors that they would consequently use Schlogl s central descriptors [20, 21]. Since volume 114, the (R, S ) nomenclature for ferrocene derivatives begins to appear, but its application is not very consequent, at least at the time where the book was written, and it is advisible to examine the orginal article rather than trust Chemical Abstract s descriptors.
