The sum of the products is 403. 403 divided by 11 yields a remainder of 7. So the check digit needs to be a 7, and it is not. The
VIN number is not valid.

The sum of the products is 277 + 5_. Some multiples of 11 are 275, 286, 297, 308, and 319. Since the check digit is X, the sum must be 10 more than one of the multiples above. Therefore, the final sum must be 285, 296, 307, 318, or 329. Placing 2 in the blank yields a final result of 297, and placing 6 in the blank yields a final result of 307, the desired number. The missing character is 6.
