I've taken the liberty of adjusting your code. (By the way, Chain is a built-in variable in the units package, so I made it lower case.)

Replaced `Do` statements with `While`.

I'm running version 10. I looked up @* in the docs but nothing came up. Found it via Composition. Thanks. Very interesting answer.

comment Improving a selection routine
@Szabolcs - yes, I would have repetitions. Michael E2's answer works for any mix of lhs's. (Thanks for your deleted answer, btw. I'll be checking out the postfix style. )

@Szabolcs - Interesting, I didn't know MinimalBy. Thanks. I meant to keep the rule intact, but the question as posted didn't require it.

Trying to extract the rule intact is more of a challenge, and would be relevant if the lhs varied. As it is, dispensing with the rule is an retrospectively obvious efficiency. ;-)
