Check Digit Verification of cas no

The CAS Registry Mumber 1021878-17-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,8,7 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1021878-17:
(9*1)+(8*0)+(7*2)+(6*1)+(5*8)+(4*7)+(3*8)+(2*1)+(1*7)=130
130 % 10 = 0
So 1021878-17-0 is a valid CAS Registry Number.

Solvent-free chemoselective cyanation of α,α- dibromoacetophenones using potassium hexacyanoferrate(II) as an eco-friendly cyanide source

Zhao, Zhouxing,Li, Zheng

experimental part, p. 5460 - 5463 (2010/11/18)

A chemoselective route for the synthesis of 2-aryl-3,3- dibromoacrylonitriles by solvent-free cyanation of α,α- dibromoacetophenones by using potassium hexacyanoferrate (II) as an eco-friendly cyanide source is developed. The merits of this procedure include avoiding the use of a strong toxic cyanide source, a catalyst, and volatile organic solvents and the high yields of the products.
