Check Digit Verification of cas no

The CAS Registry Mumber 65664-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65664-75:
(7*6)+(6*5)+(5*6)+(4*6)+(3*4)+(2*7)+(1*5)=157
157 % 10 = 7
So 65664-75-7 is a valid CAS Registry Number.

Facile Synthesis of 4-alkylphenyl 4-(4-Nitrobenzoyloxy)Benzoate (DBXNO2) and its Cyano Analog (DBXCN)

Chiang, Long Y.

, p. 137 - 142 (2007/10/02)

Two series of unsymmetrical phenylbenzoate analogs of thermotropic liquid crystals, namely, 4-alkylphenyl 4(4-nitrobenzoyloxy) benzoate (DBXNO2) and its cyano analog (DBXCN) are synthesized by a new route from benzyloxybenzoic acid.The first ester linkage of these phenylbenzoates is made by a condensation reaction between benzyloxybenzoic acid and an alkylphenol in the presence of carbodiimide and a base to give compound 6.A benzyl deprotection reaction of 6 is carried out by catalytical hydrogenation to yield compound 7.The second ester connection is performed by a condensation reaction between 7 and p-cyano or p-nitrobenzoyl chloride.This reaction sequence leads to the final products, DBXNO2 or DBXCN, in an overall yield of 50percent or 37percent, respectively.
