CAS Numbers are assigned by Chemical Abstracts Service (CAS), a division of the American Chemical Society. The CAS Registry, a database maintained by CAS, contains the authoritative list of all CAS Numbers and their chemical associations. As of May 23, 2013 the CAS Registry contained 71.6 million substances. The most recently-assigned CAS Number was 1432018â50â2. The last character of a CAS Number is a check digit derived mathematically from the preceding digits. Its purpose is to prevent human data-entry errors. Any change to the check digit or another digit has a high probability of producing an invalid CAS Number.
