This article presents divisibility tests, along the line of ``casting out nines'', in various numeration systems: base10, 12, and 20, as well as the modified base20 scheme used in the Mayan Long Count calendar. Since the latter incorporates factors of 3, besides 2 and 5, it often allows simpler tests than base10. The author gives such qualitative comparisons a spurious precision by assigning to each numeration system a score, given to four (decimal) significant figures.
