  From the first link.

  Unlike many similar numbers, Social Security numbers have no check digit.

  From the second.

  The Luhn algorithm is used to check or validate identification numbers to ensure their accuracy. Today, the algorithm verifies that a credit card or Social Security number was input and processed accurately.

    Yeah, personally, I have questions about the luhn check myself. (I am not in a state to research more this evening, unfortunately.)

      If it did, there wouldn’t be enough numbers for everyone to have a unique one.
