The last number in the given code is "2" which is the check digit. To calculate the check digit, we need to add all the other digits and take the remainder when divided by 10. 
In this case, (1+1+0+8+7+7+2+7+5+5+1+8+1+3+9+2+0+0) = 58. 
The remainder when this is divided by 10 is 8. Therefore, the check digit should be equal to 10 - 8 = 2 (as it is). 
This means all the other digits must be correct. So the answer is C, which is -15.
