Modula 10 Evaluation

Modula 10 Evaluation

This function evaluates a numeric value based on the Modula 10-algorithm.

This is commonly used in Sweden for evaluating "Personnummer" (social security
number).
function modul_10(checkValue) {
faktor = 2;
sum = 0;

check = true;
checkStr = checkValue;

checkDigit = parseInt(checkStr.charAt(checkStr.length-1));

for (index = checkStr.length-1; index > 0; --index) {
produkt = checkStr.substring (index-1, index) * faktor;
if ( produkt > 9 ) {
produkt %= 10;
produkt += 1;
}
sum = sum + produkt;
faktor = 3 - faktor;
}
cc = ((1000 - sum) % 10);
if ( checkDigit != cc ) {
check = false;
}
return check;
}
