CAS 12035-71-1 trinickel disulfide

CAS 12035-71-1 · CAS 12035-72-2 · EC 234-829-6 · Index No 028-007-00-4

Where CAS 12035-71-1 appears: every table entry that prints it among its identifiers, in the newest version of each act this record holds, and every recorded change to those entries. Many entries name a group of substances and print no number, so absence here is not absence from the law. Not legal advice.
