Tips for playing A♯7♯9 on ukulele

On ukulele the usual A♯7♯9 shape is 3244, using four fingers.

Notice the C𝄪 in A♯7♯9 (A♯ C𝄪 E♯ G♯ B𝄪): each note of the chord takes its own letter (A–C–E–G–B), so the major 3rd has to be written C𝄪 rather than D — the same key on a piano, spelled to fit the chord.
