12-17 Serial Number   6 unique digits

Position 9 is from a Check Digit calculation:

The United States of America and Canada require that the 9th position of the Vehicle Identification Number is to be used as a check digit to provide a means for verifying the accuracy of the VIN transcription. It is calculated by using the other 16 characters of the VIN to generate a single digit number.

  1. A numerical value is assigned to letters in the VIN. I, O and Q are not allowed so their positions are skipped. A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, J=1, K=2, L=3, M=4, N=5, P=7, R=9, S=2, T=3, U=4, V=5, W=6, X=7, Y=8, Z=9
  2. A weight factor is assigned to all positions of the VIN, except of course to the 9th position (the check digit itself), as follows: 1=8, 2=7, 3=6, 4=5, 5=4, 6=3, 7=2, 8=10, 10=9, 11=8, 12=7, 13=6, 14=5, 15=4, 16=3, 17=2
  3. The numerical values of the letters in the VIN are multiplied by their assigned weight factor.
  4. The resulting products from step 3 are added up.
  5. The sum of the products is divided by 11.
