To restrict to only Upper-case or Lower-case letteres
I have this regular expression
^(?:0[0-9]|1[0-3])-ARID-[0-9]{3}$
but it matches only strings like 10-ARID-278 but I want to that it should accept strings like 10-arid-257 too.
And not the strings like 10-Arid-257 or 10-ARid-257
The literal should be either ARID or arid, not the mix of upper and lower-case.

Explicitly list both uppercase and lowercase word, combining them using | (meaning OR).
^(?:0[0-9]|1[0-3])-(?:ARID|arid)-[0-9]{3}$
