Lets take a random container :
MWCU 605 978 |
|
The prefix MWCU has the value : |
|
The value of the numbers are equal to the
containernumber : |

Now make the following calculation : |
|
Now divide 7858 by 11 by long division .
The remainder is the Check Digit .
( if the remainder is 10 , the check
digit is 0 ).
