How can know the case number from cashed I-485 check?

I submitted my mother's GC application last week. I saw the I-130 and I-485 checks have been cashed by Homeland Security.

I remembered that pjiang or other masters mentioned about case number from the cashed check. May you give me a hint what the case number looks like? The words on the back of check are very blurred when viewing online.
