Is 'orchestrating' correctly used?

[Tan Elaine]

Anwar was arrested in 1998 on similar charges and later convicted before his sentence was overturned in 2004, charges he also described as politically motivated.

Mr. Najib and previous Malaysian leaders have denied orchestrating the sodomy cases against Mr. Anwar.

The Sarawak election campaign was dominated by the emergence of more allegations against Mr. Anwar.

Is 'orchestrating' correctly used? I believe it is a noun. Why is it used as a verb?

Thanks.
