CAS 57966-95-7 · CAS 166900-80-7 · EC 261-043-0 · Index No 616-035-00-5
Where CAS 166900-80-7 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.
