Calculate Digit Verification of CAS Registry Number 60558-37:
(7*6)+(6*0)+(5*5)+(4*5)+(3*8)+(2*3)+(1*7)=124
124 % 10 = 4
So 60558-37-4 is a valid CAS Registry Number.

ACTIVATION OF KETENE SILYL ACETALS BY 10-METHYLACRIDINIUM PERCHLORATE: A NOVEL CATALYSIS IN MUKAIYAMA REACTION

, p. 2405 - 2408 (1991)

10-Methylacridinium perchlorate (1) effectively promotes various reactions of ketene silyl acetals: aldol and Michael addition products are obtained with aldehydes, ketones, acetals, and α-enones.The reactions exhibit unusual dependency upon 1, namely the yields are excellent when a catalytic amount of 1 is employed whereas no desired products are accessible by the use of 1 in a stoichiometric quantity.A novel catalytic cycle is proposed.
