10 numbers is a variation of the above.
private bool Validate10Numbers(TextBox text) {
if ( text.Length < 19 ) { return false; } // basic check
string[] numbers = text.Split(',');

for(int i = 0; i < numbers.Length; i++) {
if ( !ValidateNumber(i) ) { return false;
}
return true;
}
ValidateNumber is a variation of Validate10Digits that takes a string instead
of a TextBox and then removes the initial check.

for(int i = 0; i < text.Length; i++) {
char trans = text - '0';
