Check Digit Verification of cas no

The CAS Registry Mumber 103397-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,9 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103397-09:
(8*1)+(7*0)+(6*3)+(5*3)+(4*9)+(3*7)+(2*0)+(1*9)=107
107 % 10 = 7
So 103397-09-7 is a valid CAS Registry Number.

Synthesis of esters from silyl ethers and acyl chlorides: Catalysis by quaternary ammonium chlorides

Brandaenge, Svante,Leijonmarck, Hans,Minassie, Teclay

, p. 953 - 957 (2007/10/03)

The formation of esters from silyl ethers and acyl chlorides is catalysed by quaternary ammonium chlorides, the other halide ions being less efficient. Evidence for the intermediacy of the alcohol formed by protodesilylation of the silyl ether is presented. Excellent regioselectivities (>99%) were obtained in the monoacylations of the bis-silyl ether 3 made from 1-?-benzylglycerol. Acta Chemica Scandinavica 1997.
