AR and Sedex check digit of the post office [closed]

0

Does anyone know the formula for generating the mail order checker digit, I've already contacted them, but it's 3 business days to give an answer, and unfortunately I have to finalize the system before that.

I have a lot of labels that go from JO754533210BR to JO754543210BR, but I was informed that the last 3 characters are verifiable digits, the BR is quiet, since only orders sent from Brazil are now the last number JO75453321 0 BR is the problem, because it is a verifier digit.

If someone has an example or logic, I appreciate it!

Friend checking on the internet I was able to find the mailing manual, which tells me how to calculate the verification code, check it out at page 51
