    Modulus 11 Numbering with Non-Linear Weighting

    Hi all, forgive me for my ignorance but Modulus numbering is not my strength.

    If we have the following algorithm =11-MOD(SUMPRODUCT(VALUE(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)),
    MOD(ROW(INDIRECT("1:"&LEN(A1)))-1,6)+2),11)

    The weighting is linear 2 through to 8 I am lead to believe.
    What if the weighting is not linear but actually set as the table below-:



    Digit Weight
    0 6
    1 3
    1 7
    1 9
    5 10
    6 5
    9 8
    4 4
    3 2
    3 1

    assuming the digit in cell A1 is 0111569433 and the weight is 6, 3, 7, 9, 10, 5, 8, 4, 2, 1
    How do we enter this into the algorithm as follows-: =11-MOD(SUMPRODUCT(VALUE(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)),
    MOD(ROW(INDIRECT("1:"&LEN(A1)))-1,6)+2),11) as this a non linear example

    Thank you in advance

    Please update the thread title to something more descriptive of the issue you are trying to resolve.

    And please attach a sample workbook.

    So, I have improved the thread title for you this time.

    There are instructions at the top of the page explaining how to attach your sample workbook (yellow banner: HOW TO ATTACH YOUR SAMPLE WORKBOOK). Screenshots are of little practical use as we cannot manipulate them.

    A good sample workbook has just 10-20 rows of representative data that has been desensitised. It also has expected results mocked up, worked examples where required, relevant cells highlighted and a few explanatory notes.

    Mod 11 scereenshot.jpg

    This is what I am talking about but the variable will consists of 10 digits in one cell, rather than over 10 individual cells.

    Cell O4 is just MOD(M4,11)
