The Chemical Abstracts Service (CAS) Registry has 165 million organic and inorganic chemical substances. Each substance has been assigned a unique registry number (RN) that can be used to search for information in place of searching by substance name. This number can be referred to in a few ways:

CAS Registry Number
CAS RN
CAS No.
CAS Number

The number has dashes which are considered part of the number. For example, the CAS RN for Cyclohexane is: 110-82-7. Include the dashes when searching for information in various databases, and also when citing a source of information for a substance.
