(8*9)+(7*5)+(6*0)+(5*9)+(4*0)+(3*8)+(2*4)+(1*7)=191
191 % 10 = 1
So 950908-47-1 is a valid CAS Registry Number.

Khlebnicova,Isakova,Baranovsky,Borisov,Lakhvich

, p. 1564 - 1569 (2006)

A one-pot synthesis of 2-perfluoroalkanoylcyclohexane-1,3-diones via C-acylation of cyclohexane-1,3-diones with N-perfluoroacylimidazole as an acylating agent is reported. A reaction was examined with isolated N-trifluoroacetylimidazole and with N-perfluoroacylimidazoles generated in situ from perfluorocarboxylic acid anhydrides or perfluorocarboxylic acids.
