Check Digit Verification of cas no

The CAS Registry Mumber 227014-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,0,1 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 227014-39:
(8*2)+(7*2)+(6*7)+(5*0)+(4*1)+(3*4)+(2*3)+(1*9)=103
103 % 10 = 3
So 227014-39-3 is a valid CAS Registry Number.

Enantioselective O-nitroso aldol reaction of silyl enol ethers

Kawasaki, Masanori,Li, Pingfan,Yamamoto, Hisashi

supporting information; experimental part, p. 3795 - 3797 (2009/02/07)

(Chemical Equation Presented) New nucleophiles for the O-nitroso aldol reaction in the form of readily prepared disilanyl enol ethers make this transformation more practicaland more versatile. A silver catalyst with a chiral biaryl phosphite ligand promotes the title reaction with high enantio- and regioselectivity (see scheme). R1,R2 = H, Ar; TMS = trimethylsilyl.
