About LinkBackshas anyone had a go at setting up a formula to check that a reference number
is valid via a modulus 11 check digit? i can't find that there is a function
specifically for it.

Michelle,
I just saw the algorithm in the internet
(http://docs.hp.com/en/32209-90024/apds02.html)
the following formula calculates the check digit of a number in A1.
=11-MOD(SUMPRODUCT(VALUE(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)),
MOD(ROW(INDIRECT("1:"&LEN(A1)))-1,6)+2),11)
To append the check digit to the number
=value(A1&_formula_)

Hi there, I was wondering if you can please tell me what the weighting factor is on this solution offered?
I need to be able to control the weighting factor.
Thanks
