Check Digit Verification of cas no

The CAS Registry Mumber 161949-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,9,4 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 161949-47:
(8*1)+(7*6)+(6*1)+(5*9)+(4*4)+(3*9)+(2*4)+(1*7)=159
159 % 10 = 9
So 161949-47-9 is a valid CAS Registry Number.

Synthesis of novel 3,5-dichloro-2-arylpyridines by palladium acetate-catalyzed ligand-free suzuki reactions in aqueous media

Hu, Huanan,Ge, Changhua,Zhang, Anjiang,Ding, Lisheng

experimental part, p. 3153 - 3160 (2009/12/09)

A highly efficient palladium acetate-catalyzed ligand-free Suzuki reaction of 2,3,5-trichloropyridine with arylboronic acids in aqueous phase was developed. High yields of 3,5-dichloro-2-arylpyridines, a simple Pd source, absence of ligands, and environme
