Check Digit Verification of cas no

The CAS Registry Mumber 221363-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,3,6 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 221363-48:
(8*2)+(7*2)+(6*1)+(5*3)+(4*6)+(3*3)+(2*4)+(1*8)=100
100 % 10 = 0
So 221363-48-0 is a valid CAS Registry Number.

Magnesium Chloride-Promoted Michael Addition of Dimethylsilyl Enolates to α-Enones

Miura, Katsukiyo,Nakagawa, Takahiro,Hosomi, Akira

, p. 2068 - 2070 (2007/10/03)

In the presence of MgCl2, dimethylsilyl (DMS) enolates 1 smoothly reacted with α-enones in DMF to form 1,5-diketones 3 in moderate to high yields. The Michael addition proceeded with moderate to high anti-diastereoselectivity.

Bismuth Trichloride as a New Efficient Catalyst in the Aldol Reaction and the Michael Reaction

Wada, Makoto,Takeichi, Eiji,Matsumoto, Takashi

, p. 990 - 994 (2007/10/02)

In the presence of a catalytic amount of bismuth(III) trichloride (5 mol percent), silyl enol ethers react with aldehydes at room temperature in dichloromethane to give the corresponding aldols in good yields.Silyl enol ethers also have been found to reac
