Check Digit Verification of cas no

The CAS Registry Mumber 18944-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,4 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18944-91:
(7*1)+(6*8)+(5*9)+(4*4)+(3*4)+(2*9)+(1*1)=147
147 % 10 = 7
So 18944-91-7 is a valid CAS Registry Number.

Facile bromination of o-benzylidene sugar and thf ethers with NBS in chloroform in the presence of AIBN

Raina, Sushil,Srivastava, Kamal K.,Sampath Kumar,Singh, Vinod K.

, p. 121 - 125 (1996)

N-Bromosuccinimide in chloroform in the presence of a catalytic amount of AIBN is found to cleave O-benzylidene sugar into bromobenzoate in efficient manner. THP-ethers were cleaved into bromides and bromo-esters in high yield.

Ring Opening of 2,3-, 3,4-, and 4,6-O-Benzylidene Acetals of Pyranosides by Photobromination with Bromotrichloromethane

Chana, Jasbir S.,Collins, Peter M.,Farnia, Farnoosh,Peacock, David J.

, p. 94 - 96 (2007/10/02)

2,3-, 3,4-, and 4,6-O-Benzylidene pyranoside dervatives on photobromination in bromotrichloromethane yield bromo-deoxy-pyranoside benzoates regio- and stereo-specifically which, for the acyl derivatives of the 2,3- and 3,4- acetals, is superior to their r
