CAS Number Cross-Reference List

The reader should note that the chemical entries are listed by their names in alphabetical order. The HAP entries are listed in the order found in Section 112 under the 1990 Clean Air Act Amendments. Each entry is also listed in alphabetical order in Appendix A Alphabetical List. The reader may use the alphabetical list in Appendix A to find a chemical. If the name of the chemical being sought cannot be found in Appendix A, the reader may employ the CAS Number Cross-Reference List in Appendix B to help locate the chemical. 

The CAS number cross-reference list can be found in Appendix B. It provides the names of the regulated chemical entries in CAS number order. The CAS number follows the form XXXX-XX-X. The field on the left has a variable number of digits. The middle field always has two digits and the field at the right, one digit. The numbers are ordered first by the field at the left, second by the middle field and last by the field at the right. For more about CAS numbers, see the explanation of the CAS field below. 

This easy to use two-volume handbook presents chemical safety and health information on nearly 1500 toxic and hazardous chemicals. The utility of the 4th edition has been enhanced by addition of eight appendices five cross index chemicals by CAS number, molecular formula, synonyms and trade names, DOT ID, and RTECS one is a glossary of terms used one lists oxidant chemicals and one contains a list of confirmed and suspected carcinogens. References are included. Also available online. 

All substances mentioned in a particular Chemical Abstracts volume are listed in the Formula Index. Each molecular formula is followed by the various systematic CA Index Names, the appropriate CAS Registry Number in square brackets and the corresponding abstract numbers. Where numerous abstract citations are given for one substance name, so that subdivisions are necessary in the Chemical Substance Index, a cross-reference to the Chemical Substance Index is given.
