Check Digit Verification of cas no

The CAS Registry Mumber 22424-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,2 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22424-65:
(7*2)+(6*2)+(5*4)+(4*2)+(3*4)+(2*6)+(1*5)=83
83 % 10 = 3
So 22424-65-3 is a valid CAS Registry Number.

Copper-Free Double Silylation of 1,2-Dibromobenzenes Using a Mg/LiCl/DMI System

Kitamura, Tsugio,Yamada, Rin,Gondo, Keisuke,Eguchi, Nobuo,Oyamada, Juzo

, p. 2495 - 2500 (2017/05/22)

The reaction of 1,2-dibromobenzenes with chlorotrimethylsilane efficiently proceeded in the presence of Mg and LiCl in DMI under mild conditions, giving 1,2-bis(trimethylsilyl)benzenes in good to high yields. The reaction of 1,2-dibromobenzenes with chlorodimethylsilane under the same conditions afforded the corresponding 1,2-bis(dimethylsilyl)benzenes in high yields. Functional group transformations of 1,2-bis(trimethylsilyl)benzene were conducted to demonstrate the synthetic utility.
