EC 243-867-2 Nickel oxalate [1]
CAS 547-67-1 · CAS 20543-06-0 · EC 208-933-7 · EC 243-867-2 · Index No 028-039-00-9
Where EC 243-867-2 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.
