(7*4)+(6*0)+(5*4)+(4*4)+(3*6)+(2*0)+(1*9)=91
91 % 10 = 1
So 40446-09-1 is a valid CAS Registry Number.

D'Auria, M. Valeria,Paloma, Luigi Gomez,Minale, Luigi,Riccio, Raffaele,Debitus, Cecile

, p. 2149 - 2152 (1991)

Two 3 β - methoxy secosteroids, named jereisterol A and B were isolated from the pacific sponge Jereicopsis graphidiophora Levi & Levi. Their structures, which combine rare 3 β-methoxy and seco features, were determined as (24 R) 24-methyl-3β-methoxy-8α,9α-oxido-8,9-secocholesta-7,9 (11)-diene (1) and (24R) 24-methyl-3β-methoxy-8,14-secocholesta-8,14-dione (2).
