Appendix G: CAS Registry Number Index Eighth Report on Carcinogens

Appendix G CAS Registry Number Index

In the CAS Registry Number (CASRN) index are listed the chemical names and Chemical Abstracts Service (CAS) Registry Numbers or all entries in the Eighth Report on Carcinogens. The CASRN is simply a unique identification number for a specific chemical substance (like personal identification by the Social Security Number). The CAS Registry System publishes a Registry Handbook (updated yearly) that contains the names and CASRNs of all chemical substances that have been reported since 1965. The Registry Handbook also has a Common Name Index that links about 600,000 common names to 370,000 CAS numbers, and is compose of 2 sections: Name and Number. The Name Section links common substance names (arranges alphabetically) to their corresponding CAS numbers and molecular formulae. The Number Section links the CAS number (arranges numerically) to the molecular formula, Chemical Abstracts index name, and the common name. (NOTE: Because this is a large file, selecting an agent's profile from this list opens a separate web page to allow viewers to return to the list without having to reload the file.)
