Can you also find out the Guard digits, as described here?: http://www.rskey.org/~mwsebastian/miscpr...digits.htm
(Basically by subtracting 9 from the result and multiplying by 1000000. This pushes the guard digits to the front). You can look in the list on the linked webpage which (or if) calc produces the same results.
