CCI Now Searchable in CAS REGISTRY(SM)

03. April 2018

As part of STN’s ongoing efforts to make your searching capabilities as comprehensive as possible, STN has made the Component Class Identifiers (/CCI) field in CAS REGISTRY searchable. This latest update is good news for anyone working with multi-component substances, and applies to the entire REGISTRY file.

Now the multi-component substances retrieved by your search will include matches based on individual components as well as the overall substance(/CI field). In REGISTRY, use the /CI search code to find substances characterized as: alloys, mixtures, minerals, ring parents and more.

Refer to the REGISTRY Database Summary Sheet (DBSS) and the help messages for a refresher on the /CI search field.
