check digit scheme: mod 10 or what?

[Markus]

below is the list of hypothetical student numbers, the last digit is the
check digit. What I'd like to know is the check digit scheme used. Mod 10
algorithm doesn't work. I tried Verhoeff algorithm but it's to complicated
for me. Here's the first 20 in the series... please help me. i've been trying
to figure this out since yesterday. trial and error is so frustrating
already. i'd appreciate also if someone can show me how to implement in vb

Hello Markus,

So far it looks like a Mod 11 scheme with weight 4 on 11th digit and
weight 8 on 10th digit.

It dont know such a system and I could not find it in the web.

Provide some more numbers with different digits for leftmost 9 digits.

Regards,
Bernd
