Chemical Names & CAS Registry Numbers

Searching chemicals by CAS Registry Number can help eliminate the confusion of searching by name. Because many chemicals have multiple names, you can narrow your search more quickly using the CAS number method – the search result will include every name associated with a particular chemical.
You can find the CAS number for a chemical through a variety of resources:
- FracFocus includes the CAS numbers in our Find a Well form.
- An alphabetical list, organized by the chemical’s function, is included below.
- Several websites include a CAS number database:
