The U.S. Social Security Number doesn't HAVE a check digit. In that regard

it's like a telephone number, a street address, or the number of Coke 
bottles in a carton. You can apply your method, but it won't work.

A modulo-11 scheme, as you point out, sometimes generates a check-digit of

"X." That's why all modern check-digit methods use modulo-10 so that the 
result is always numeric. Further, the only modulo-11 method in common use

that I know of is the ISBN (presently being phased out in the book 
industry).
