i think there are several examples of both the VIN and the Part Number sequence with the check sum in this thread on the first page.

I spent some time trying various parameters, but was not able to calculate the CRC or find the algorithm. The algorithm can be anything. Also, only a part of the VIN number might be used for the calculation. It doesn't even have to be a CRC algorithm. Can just be addition of all the hex values + something. Who knows.

I think it would be good if we could get at least 4 VIN numbers and corresponding checksums. Right now I only found 2 VINs and 2 part numbers in this thread.
