Answer:
Answer: 6
Step-by-step explanation:
1. Add together the value of all of the digits in odd positions (digits 1, 3, 5, 7, 9 and 11). 2 + 0 + 5 + 9 + 3 + 7 = 26
2. Multiply that number by 3. 26 * 3 = 78
3. Add together the value of all of the digits in even positions (digits 2, 4, 6, 8 and 10). 3 + 1 + 6 + 1 + 5 = 16
4. Add this sum to the value in step 2. 78 + 16 = 94
5. Take 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. 94 + 6 = 100 The check digit is therefore 6.
