There are divisibility tests by 3, 9, and 11 as well as Divisibility tests for 2, 4, and 8 (and other powers of 2) which are relatively easy, and divisibility by 5 is even easier.
Explore: What else is out there? Why do we not need a separate divisibility test for 6 or 22 or 36? Is there a divisibility-by-7 test analogous to the ones for 9 and 11?

Identifying individuals with a high risk of Alzheimer’s disease
usually involves a long series of cognitive tests. However,
researchers have developed a 7-Minute Screen, which is a quick and
easy way to accomplish the same goal. The question is whether the
7-Minute Screen is as effective as the complete series of tests. To
address this question, Ijuin et al. (2008) administered both tests
to a group of patients and compared the results. The following data
represent results similar to those...
