Is this correct?

Numbers *n* such that the Roman numeral representation has at least
one nontrivial divisor of *n* as a substring

8, 12, 15, 18, 20, 22, 24, 25, etc.

I've bolded some of the characters, but it may or may not go through:

V*II*I, X*II*, X*V*, XV*II*I, *X*X, XX*II*, XX*IV*, XX*V*, etc.

Not getting OEIS results, but I haven't tried variations of this yet.
