Check Digit Verification of cas no

The CAS Registry Mumber 99329-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,2 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99329-28:
(7*9)+(6*9)+(5*3)+(4*2)+(3*9)+(2*2)+(1*8)=179
179 % 10 = 9
So 99329-28-9 is a valid CAS Registry Number.

Solvent Effects on Isomer Distributions and Relative Rates in Friedel-Crafts Benzylation and Benzoylation of Dibenzofuran Derivatives

Keumi, Takashi,Nakamura, Masatoshi,Kitamura, Masao,Tomioka, Naoto,Kitajima, Hidehiko

, p. 909 - 914 (2007/10/02)

The positional reactivity order in Friedel-Crafts benzoylation and benzylation of dibenzofuran (DBF) is found to be 2 > 3 > 1 >= 4.Both the partial rate factors and the positional selectivity for the benzylation of DBF are very low compared with those of
