I looked up the term “86’ed” and found this:

“
eigh·ty-six
/ˌādēˈsiks/
verbINFORMAL•NORTH AMERICAN
past tense: 86ed; past participle: 86ed
1.
eject or bar (someone) from a restaurant, bar, etc.
“they were accused of cheating, and eighty-sixed from their favorite casino”
2.
reject, discard, or cancel.
“the passwords will be 86ed by next October”
Origin

1930s (as a noun, used in restaurants and bars to indicate that a menu item is unavailable or that a customer is not to be served): perhaps rhyming slang for nix1.
“

As for that pill name “RU486”, that acronym always got me thinking it read “are you (something something something)” and I wasn’t sure what the “something”s were; your take on it clears it up !

I still hear '86' used in restaurants. I've even seen it written over unavailable items listed on the specials board. It's great shorthand for use in a busy place.
