Registry Handbooks

Registry Handbook, Registry Humber Update, (1965—1990), 11119-73-6, American Chemical Society, Washington, D.C. 

Part I contains entries referring to the names of compounds according to the Chemical Abstracts Systematic Nomenclature (see Index Guide, Chemical Abstracts vol 76, 1972) The systematic name is followed by Chemical Abstracts Registry Number m brackets (see Chemical Abstracts Registry Handbook 1965-71 and Supplements) and page number... 

Since 1965, CA has assigned a Registry Number to each unique chemical substance. This is a number of the form [766-51-8] that remains invariant, no matter what names are used in the literature. More than 10 million numbers have already been assigned and thousands are added each week. Registry Numbers are primarily for computer use. All numbers so far have been pubUshed with the CA preferred names in a multivolume Registry Handbook . 

Some of the rigidly systematic names selected by the Association for Science Education for their nomenclature list in 1985 from the IUPAC possibilities, and some of the systematic indexing names used by Chemical Abstracts since 1972, are given as synonyms in the Index of Chemical Names (Appendix 4). This should assist those coming into industry and research with a command of those nomenclature systems but who may be unfamiliar with the current variety of names used for chemicals. The inclusion where possible of the CAS Registry Number for each title compound should now simplify the clarification of any chemical name or synonym problems, by reference to the Registry Handbook or other CAS source.

Eollowing the introduction of the system of CAS registry numbers in 1965 (see Chapter 9), CAS published the Registry Handbook—Number Section. The initial handbook covered the period 1965-1971 (registry numbers 35-66-5 to 33913-68-7). Annual supplements of registry numbers were published from 1972 to 2001 (registry numbers 33913-69-8 to 380148-63-0), when publication... 

Entries in the Registry Handbook list CAS registry numbers in numerical sequence, and then-associated CA Index Names and molecular formulae. Concomitantly with the printed edition, CAS developed an online searchable database of registry numbers, CAS Registry. By April 2010, this database contained the details of over 53,000,000 organic and inorganic substances and 61,722,079 sequences, and the most recent CAS registry number was 1217435-73-8. 

The CAS Registry Handbook (Number Section) and supplements should be consulted for obtaining the substance name and elemental formula corresponding to a Registry Number.

The Registry Handbook—Number Section provides the CA Index names and the molecular formulas for more than 15 million substances. The base book covers 1965—1971. Additions are provided in annual supplements. 

CHEMICAL ABSTRACTS SERVICE Division of the Ameriean Chemieal Society, 2540 Olentangy River Road, Columbus OH 43210, (614) 447-3731. Established 1907. Over 13 million abstracts of chemical related literature and patents, and over 16 million material records. Publishes numerous abstracts, current awareness bulletins, and registry handbooks. Most literature now also available on CD-ROMs and online through STN International, which has 200 databases available. Connected to international databases. 

Present name attributed by CAS Registry Handbook Number Section-1995... 

The Registry Handbook - Number Section, also available in microform, lists CA index names and molecular formulas of all the chemical substances recorded in the CAS Registry. The Registry Handbook - Common Names, in microform, links common names with CA index names for some selected 1.5 million substances. 

The Registry Handbook - Number Section contains all the CAS Registry Numbers so far assigned. It is, therefore, a part of the CAS Registry database, which was described in Sect. 1.3.1. 

The Registry Handbook - Common Names consists of two parts ... 

Not all the substances listed in the Registry Handbook - Common Names have been mentioned in Chemical Abstracts, as the Chemical Abstracts Service also awards CAS Registry Numbers to substances which have been included in other publications, e.g. Colour Index, Merck Index or from other organizations such as the BioSiences Information Service, but which have not been described in the primary literature. Or these substances were mentioned in the literature before the computer supported publication of Chemical Abstracts started, i.e. before 1967.
