How to derive the CHECK DIGIT of EAN Codes?

[xlmaniac]

Dear All,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
I am trying to calculate the check digit(13<SUP>th</SUP> digit in the EAN) for my company’s EAN codes based on the 12 digit prefixed number.<o></o>
The method of calculating of the CHECK DIGIT(13<SUP>th</SUP> & last digit) of EAN is as follows:-<o></o>
1)The even position number needs to be multiplied by 3.<o></o>
2) The even position number needs to be multiplied by 1.<o></o>
3)The result needs to be added(1+2).<o></o>
4)The result needs to be substracted from the nearest equal or higher multiple of ten.<o></o>
<o></o>
I have put one formula to derive the CHECK DIGIT which is yielding the correct result.<o></o>
Just curious if there is any shorter & smarter formula than the one that I have put.<o></o>
The sample data is as follows:-<o></o>

Try

=MOD(10 - MOD(SUM(MID(A1, {1,2,3,4,5,6,7,8,9,10,11,12}, 1) * {1,3,1,3,1,3,1,3,1,3,1,3}), 10), 10)
