Add together the value of all of the digits in odd positions (digits 1, 3, 5, 7, 9 and 11).6 + 9 + 8 + 0 + 0 + 9 = 32Multiply that number by 3.32 * 3 = 96Add together the value of all of the digits in even positions (digits 2, 4, 6, 8 and 10).3 + 3 + 2 + 0 + 3 = 11Add this sum to the value in step 2.96 + 11 = 107Take the number in Step 4. To create the check digit, determine the number that, when added to the number in step 4, is a multiple of 10.107 + 3 = 110The check digit is therefore 3.
