Check Digit Verification of cas no

The CAS Registry Mumber 71777-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,7 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71777-55:
(7*7)+(6*1)+(5*7)+(4*7)+(3*7)+(2*5)+(1*5)=154
154 % 10 = 4
So 71777-55-4 is a valid CAS Registry Number.

p,p'-Dinitrobenzhydryl Ethers, Acid and Base Stable Protecting Groups, Which Are Readily Removable in the Presence of Benzyl and Monomethoxytrityl Functions

Just, George,Wang, Zhi Yuan,Chan, Laval

, p. 1030 - 1033 (2007/10/02)

BF3-catalyzed reaction of alcohols with bis(p-nitrophenyl)diazomethane gave the corresponding DNB ethers, from which blocking groups were selectively removed by catalytic hydrogenation using platinium or nickel boride or by chemical reduction, followed by mild acid hydrolysis (e.g., pH 4).
