PGI-9 vs PGI-72 for Pro9500 Mk II

[jaffedoc]

I use a Pro9500 Mark II that still works fine, but it's getting harder to get the PGI-9 ink.  I recently got a 10-pack of PGI-9 that had a PGI-72 Matte Black in place of the PGI-9.  Are they the same?  If so, can I use PGI-72 for all colors?

Cartridges have chips, so it is unlikely it will work. Did you buy it from an authorized canon dealer? You should return it.

Thanks--I bought it online from Canon USA...on hold with them right now.
