Check Digit Verification of cas no

The CAS Registry Mumber 431892-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,8,9 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 431892-74:
(8*4)+(7*3)+(6*1)+(5*8)+(4*9)+(3*2)+(2*7)+(1*4)=159
159 % 10 = 9
So 431892-74-9 is a valid CAS Registry Number.

One-pot synthesis of unsymmetrical benzils and N-heteroarenes through nucleophilic aroylation catalyzed by N-heterocyclic carbene

Suzuki, Yumiko,Murofushi, Mai,Manabe, Kei

, p. 470 - 473 (2013/02/25)

An efficient one-pot synthesis of various unsymmetrical benzils via N-heterocyclic carbene (NHC)-catalyzed aroylation of N-phenylimidoyl chlorides with aromatic aldehydes followed by acidic hydrolysis has been developed. The one-pot procedure was extended to synthesis of quinoxalines and pyrazines by condensation/annulation of unsymmetrical benzils generated in situ with diamines.
