CAS numbers for selected chemicals with links to safety data
The list of CAS numbers once held at this web page grew to be large and
cumbersome, so it
has been replaced by a number of sub-lists which are quicker to
download and easier to search through
(follow this link)
If your site has a link into this page, we suggest that
you replace it with a link to
/newcas.html
which will be maintained indefinitely.
