(7*2)+(6*2)+(5*4)+(4*7)+(3*4)+(2*7)+(1*0)=100
100 % 10 = 0
So 22474-70-0 is a valid CAS Registry Number.

BEITRAEGE ZUR CHEMIE DES IODOPENTAFLUORIDS. TEIL IV. IF5 EIN SELEKTIVES OXIDATIVES FLUORIERUNGSMITTEL FUER ORGANOPHOSPHOR(III)-VERBINDUNGEN

Frohn, H. J.,Maurer, H.

, p. 73 - 82 (1986)

Aryl-and alkylphosphines R3P, R2PF, R2PCl, and RPCl2 are oxidized by IF5 to the corresponding fluorophosphoranes in a fast one step-reaction at or below 0 deg C.The only coproduct is elemental iodine.IF3 or IF as reduction products of IF5 are not observed.Fission of P-C - bonds by from I2 and IF5 is negligible under reaction conditions.In alkylfluorophosphoranes fluoride donor-acceptor-interactions between fluorophosphoranes and IF5 are observed.
