Sorting out all repeat numbers

Could anyone explain why the code I'm using is only including repeat numbers with "0" in the number and miss 5 other repeat numbers (highlighted in magenta)?

See sample...

Is there any reason as to why the likes of 022, 066, 077 are not highlighted ?

Assuming the above to be an oversight and return of 902 an error then a more straightforward approach would be to compare the characters:

The above would highlight triples also - if that's not required the above can be altered (revert to addition of equality tests and test for result of 2)

The existing method fails as it assumes a string containing duplicate digits will either be a multiple of 11 or less than 11 (001-010)
