Check Digit Verification of cas no

The CAS Registry Mumber 190200-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,2,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 190200-82:
(8*1)+(7*9)+(6*0)+(5*2)+(4*0)+(3*0)+(2*8)+(1*2)=99
99 % 10 = 9
So 190200-82-9 is a valid CAS Registry Number.

Regioselective synthesis of 1,5-diaryl-1H-imidazoles by palladium-catalyzed direct arylation of 1-aryl-1H-imidazoles

Bellina, Fabio,Cauteruccio, Silvia,Mannina, Luisa,Rossi, Renzo,Viel, Stephane

, p. 3997 - 4005 (2005)

A variety of 1,5-diaryl-1H-imidazoles have been regioselectively synthesized by direct coupling of 1-aryl-1H-imidazoles with aryl iodides or bromides in DMF in the presence of CsF as the base and a catalyst precursor consisting of a mixture of Pd(OAc)sub
