For example, a student's age might be 14, but if 11 is entered it will be valid but incorrect. For example, a secondary school student is likely to be aged between 11 and 16. The two exceptions are: If the remainder is 0 and the result is 11 the check digit is 0, not 11. An existence check is a data validation check that. Validation is an automatic computer check to ensure that the data entered is sensible and reasonable.

The remainder is subtracted from 11 to give the check digit. The results of these calculations are added together to give a total This calculation gives the value of the check digit which is then added as an extra digit to the end of the number.Д¬alculating check digits using the modulus-11 methodД®ach digit is assigned a weight starting at 2 with the right hand digit

The value of a check digit is worked out by performing a calculation using the individual digits that make up a number.
