I have a question.
How can I find the DNAS Disc ID of a PS2 disc?

You need a PS2 console that has the ability to run homebrew programs, and run a program such as ID Dumper (https://www.psx-place.com/resources/id-dumper.455/) that will get it.
This ID is not required at all for submission.

Let me explain my question.
I'm developing a system for locating discs based on their creation. From what I'm observing, the DNs appear to be "unique" based on pressing batches, and I'm trying to confirm this suspicion.

If I could confirm this theory, we'd be able to create a lost CD locator.

I'd just have to cross-reference the serial numbers with the barcodes and DNs to locate unknown versions.

Thanks for your help.

It was my understanding that the first 3 bytes of the DNAS ID is unique to each disc, not just pressing run. Similar to the "Disc ID" for PS3 discs.
DNAS ID began to be used on PS2 discs around 2002.
It is located somewhere near the beginning of the disc, perhaps written in the 'wobble' that Sony likes to use. In any case, it's not readable via normal PC disc drives/commands.

If your interest is in a 'lost CD locator', also checkout my attempt at a complete PS1/PS2 Sony serial index: https://sony.redump.info/

Thanks for the information.
I'm trying to create a "theory" for locating the discs.
The DNS is associated with the creation of the disc itself. However, the SLES serial number association at Sony is done in the previews and betas, which already have the code assigned in the case of TLES. Therefore, I'm also analyzing the beta data to try to close the search loop. In this case, for example, I think I've found SLES 50063, which I believe could be the canceled PS2 version of 007: The World Is Not Enough.
But at the moment, I don't have enough data to 100% confirm this theory, which is why I wanted the DNS data to further narrow down the possibilities.

I'm currently cross-referencing the creation dates of the known betas, the release dates (or first news confirming the PS2 version of the game), and the executable dates for the games "close" to the breach.

Hopefully, with the DNS data, I can improve my theory.

Thank you very much.
