After getting into the ringed copy protection stuff, I had to try if creating a verification is truly possible.
And here we go - I have a perfect match for http://redump.org/disc/81628/. Hashes and ring codes are a perfect match.
Initially dumped with redumper, skipping the error range with a bit of safety margin since my Plextor drives are not good at reading close to the ring.
The ring was read with CDArchive and my Lite-On drive.
