ARIN makes available a list of prefixes with OriginAS. I don't know if other RIR's do.

How is that list generated?

I'm not aware of any tight coupling between address assignment and AS assignment that binds anybody to advertise particular routes with particular origins, at least at the time that either is assigned/ allocated by an RIR/LIR.

Without such a coupling, would a report along the lines that you suggest implicate the advertisement, or the "whois record" (whatever that means)?
