How to confirm a source acronym (for SN)?

I might have acquired a source referred to as DMC, but I admit I don't have total confidence it's the one being referred to. And I'm not very sure whether it's legit and the SN is as pure as it claims.

Thank you @DepressedDude, it seems to be the one I have. I wanted to reply and send the full path in DMs for confirmation but it seems as though any messages I try to send there are flagged as spam and so not allowed to be sent.
