Check Digit Verification of cas no

The CAS Registry Mumber 935554-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,5,5,5 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 935554-58:
(8*9)+(7*3)+(6*5)+(5*5)+(4*5)+(3*4)+(2*5)+(1*8)=198
198 % 10 = 8
So 935554-58-8 is a valid CAS Registry Number.

Stereocontrolled glycoside and glycosyl ester synthesis. Neighboring group participation and hydrogenolysis of 3-(2′-benzyloxyphenyl)-3,3- dimethylpropanoates

Crich, David,Cai, Feng

, p. 1613 - 1615 (2008/02/03)

Equation presented The 2-O[3-(2′-benzyloxyphenyl)-3,3- dimethylpropanoate] and 2-O-[3-(2′-benzyloxy-4′,6′- dimethylphenyl)-3,3-dimethylpropanoate] esters enable the synthesis of a range of β-glucosides and α-mannosides through neighboring participation in excellent yield, and are removed by hydrogenolysis in concert with the cleavage of benzyl esters in the presence of other esters making them particularly well suited to the stereocontrolled synthesis of glycosyl esters.
