Specifications

The calculations for determining the Mod 10 Check Digit character
are as follows:
1. Start at the first position and add the value of every other
position together.
0+2+4+6+8+0=20
2. The result of Step 1 is multiplied by 3.
20x3=60
3. Start at the second position and add the value of every other
position together.
1+3+5+7+9=25
4. The results of steps 1 and 3 are added together.
60+25=85
5. The check character (12th character) is the smallest number
which, when added to the result in step 4, produces a multiple of 10.
85+X=90(next higher multiple of 10)
X=5Check Character
