Need to convert a asp.net validation code into a jQuery validation
//this function multiplies digits 1,4,7 by 3, digits 2,5,8 by 7, and 3,6,9 by 1, and
//adds the results together. If the total is evenly divisible by 10, then the check digit is ok
//otherwise, it is not. example "good" trn = 263181368
if (sTrn.Length < 9) return false;
int[] multipliers = new int[3] { 3, 7, 1 }; //multiply each digit by one of these numbers
int s = 0;
int m = 0;
for (int i = 0; i < 9; i++)
{
s += int.Parse(sTrn.Substring(i, 1)) * multipliers[m];
m = ++m < 3 ? m : 0; //reset to first multiplier
}
return (s != 0 && s % 10 == 0) ? true : false;
