hi all
I need to find art number of some chemical compounds and I don't know what is an art number, and how I can find art number for a chemical compound such as anhydride acetic or etc.
anyone can help?

I think it stands for article number.  So You have to browse the webside of the chemical supplier to find this number, because evey shop has it own.

thanks for your reply, I have searched some supplier's website such as Merck, sigma aldrich and also some databases such as chemspider and pubchem but I didn't find anything I doubt that this number must be only in printed merck catalouge! but I'm not sure
