A#9 chord
The A-sharp dominant ninth chord (abbreviated A#9 chord) is a five-note chord consisting of the notes A♯, C, E♯, G♯, and B♯. The chord is formed by adding a major ninth to the A-sharp dominant seventh chord.
In practice, the fifth (E♯) is sometimes omitted from the A#9 chord because it's not always possible to play all notes simultaneously.
