Check Digit Verification of cas no

The CAS Registry Mumber 99779-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,7 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99779-63:
(7*9)+(6*9)+(5*7)+(4*7)+(3*9)+(2*6)+(1*3)=222
222 % 10 = 2
So 99779-63-2 is a valid CAS Registry Number.

PREPARATION OF 7,7,8,8-TETRACYANOQUINODIMETHANE AND ITS DERIVATIVES

Yamaguchi, Shunro,Hanafusa, Terukiyo

, p. 689 - 690 (1985)

The reaction of terephthaloyl chloride with cyanotrimethylsilane in the presence of pyridine gave 1,4-bis(dicyanotrimethylsiloxymethyl)benzene, which was treated with POCl3-pyridine to afford tetracyanoquinodimethane (TCNQ) along with its dichloride.Similarly, 2,5-dimethyl-TCNQ and 2-bromo-TCNQ were prepared from the corresponding tetraphthaloyl chlorides.
