So is the CAST family of ciphers used for anything?

Studying for my CISSP and there is a section here but have not run across CAST before.

@ropman76 Never seen it implemented. Some GPG and PGP defaults and we don't use them.
You won't see it in any US federal or related system.
Hmmmm...it seems to be approved for Canada.
Memorize it for the exam (or don't there'll be, if any, maybe 1 or 2 questions on it.) You can guess and maybe get it right or take the hit.
