Chemical Abstract Service Registry Number

NOTE ON CHEMICAL ABSTRACTS SERVICE REGISTRY NUMBERS AND NOMENCLATURE... 

The Chemical Abstracts Services Registry Number and lUPAC nomenclature for PVP are [9003-39-8] and l-ethenyl-2-pyrrohdinone homopolymer, respectively however, it is known by a variety of approved names by foreign and domestic regulatory authorities. For example ... 

Chemical Abstract Service Registry Number for a typical example of the sensitizer listed. See Figure 7 for some stmctural formulas. 

Almost all the entries in Chapters 4, 5 and 6 have CAS (Chemical Abstract Service) Registry Numbers to identify them, and these have been entered for each substance. Unlike chemical names which may have more than one synonymous name, there is only one CAS Registry Number for each substance (with only a few exceptions, e.g. where a substance may have another number before purification, or before determination of absolute configuration). To simplify the method for locating the purification of a substance, a CAS Registry Number Index with the respective page numbers has been included after the General Index at the end of the book. This will also provide the reader with a rapid way to see if the purification of a particular... 

CAS Number - Chemical Abstracts Service Registry Number A CAS (Chemical Abstracts Service) Registry Number is a unique identifier that tells you, for example, that aeetone and dimethyl ketone are actually the same substance. The Chemical Abstracts Service is a division of the American Chemical Society. OSHA only requires certain items on an MSDS and a CAS number is not one of them. However, authors of MSDS s are allowed to add additional information, such as the CAS number, if they desire. The numbers you see on trucks on the highway are not CAS Numbers, butU.S. Department of Transportation (DOT) codes, which are not necessarily specific to each chemical. Their aim is to assist emergency responders. 

Compounds are identified by an IUPAC approved name [93-ano-l], the empirical molecular formula, and the Chemical Abstracts Service Registry Number. A summary table is available for each compound which includes the reported temperature and density values, an assigned uncertainty for the density, the difference between the observed and smoothed density values and an index key to the source of the data. A complete list of references, identified by the index keys, appears at the end of the volume. 

CAS Chemical Abstracts Service registry number. It is unique for each chemical without inherent meaning that and is assigned by the Chemical Abstracts Service, a division of the American Chemical Society. It allows for efficient searching of computerized databases.

For chemical exposures, the Chemical Abstracts Services Registry Number, the latest Chemical Abstracts Primary Name and the lUPAC Systematic Name are recorded other S5mon5nns are given, but the list is not necessarily comprehensive. For biological agents. 

All test and reference items should be identified with a Chemical Abstracts Service registry number or other unique code. Where test items are novel compounds supplied by the sponsor of the study, there should be an agreed-upon identification system to allow the item to be tracked through the study. The composition and concentrations of prepared solutions should be known and recorded. A sample for analytical purposes of each batch of test item should be retained for all except short-term studies. This requirement has the potential to overload storage facilities very quickly, and some sensible arrangement must be made to archive samples of importance, while not giving an inspector cause to worry about inappropriate disposal of items.

CHEMICAL ABSTRACT SERVICE REGISTRY NUMBER (CAS). This universally used number permits use and comparison of data on a given material no matter the synonym with which it might be published. It will, in fact, permit absolute identification of a compound with all of its synonyms. CAS numbers also facilitate extraction of information from computerized data bases. See also Chemicals (Number of).
