Here's a less verbose version which passes your test cases:

start, stop, stride = slc.indices(len)
if stride < 0:
return (start >= index > stop) and ((start-index) % -stride == 0)
else:
return (start <= index < stop) and ((index-start) % stride == 0)
(Hint: help(slice) is your friend.)
I should really think about abandoning my strategy of doing everything
the hard way.
