94 % 10 = 4
So 7171-64-4 is a valid CAS Registry Number.

Reactions of pyrazoles and pyrazolium salts with complex metal hydrides and organometallic reagents. Synthesis of pyrazolines and pyrazolidines

Cuadrado, Purificacion,Gonzalez-Nogal, Ana M.,Martinez, Senen

, p. 8585 - 8598 (2007/10/03)

2-Pyrazolin-4-oximes have been synthesized by reaction of 4-nitroso- and 4-nitropyrazoles with complex metal hydrides and organometallic reagents. Furthermore, 4-nitropyrazolium tetrafluoroborates are reactive substrates towards organolithium and Grignard
