How to find out catalogue number from JAN?

[Datschge]

At Sofmap there's currently an offer for a "Tales of Series Battle Arrange" CD credited to Sakuraba (http://www.sofmap.com/product_detail/exec/_/sku=11036657/-/) to be released on August 27th. The bad thing is that Sofmap (just like Amazon) doesn't list any catalogue number but only the JAN, and I can't find any info on this product elsewhere either.

So how does one find out catalogue number from JAN/EAN? Is that even possible?

Edit: Looks like PV over at GMRonline got it somewhere already...

Unlike some western album releases, Japanese catalogue numbers usually don't correspond with their JAN/EAN codes at all.

And apparently the Team Entertainment website doesn't have the album page up for that catalogue number yet.
