5.0 CHECK DIGIT — Method of calculation
The 'Check Digit' for each wagon is calculated using a six-step algorithm based on ten
digit wagon number arrived at as indicated below.
Step — 1 Starting from the left, add , all the Characters in the even position.
S1=C2+C4+C6+C8+C10
Step — 2 Multiply the sum by 3 to get 3S1
Step — 3 Starting from the left, add all the Characters in the odd position.
S2=C1+C3+C5+C7+C9
Step — 4 Add the sum of step 2 to the sum of step 3 to get S4=3S1+S2
Step — 5 Round this total up to the next multiple of 10.
Step — 6 The check digit is the number required to be added to round up to the next
multiple of 10.
