Check Digit Verification of cas no

The CAS Registry Mumber 91787-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,8 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91787-05:
(7*9)+(6*1)+(5*7)+(4*8)+(3*7)+(2*0)+(1*5)=162
162 % 10 = 2
So 91787-05-2 is a valid CAS Registry Number.

Solvent Effects on Isomer Distributions in Acylation of 1,2,3,4-tetramethyldibenzofuran : Regiospecific Solvation of the Intermediate ?-Complex

Keumi, Takashi,Yagi, Yumiko,Kato, Yoko,Taniguchi, Rikio,Temporin, Makoto,Kitajima, Hidehiko

, p. 799 - 806 (2007/10/02)

A large solvent effect is observed in Friedel-Crafts acylation of 1,2,3,4-tetramethyldibenzofuran (TMD). 8-Acyl-TMD is by far the major product in nitrohydrocarbons while 7-acyl-TMD is favoured in chlorohydrocarbons and is the major product in many cases.
