146537-22-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 146537-22-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,5,3 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146537-22:
(8*1)+(7*4)+(6*6)+(5*5)+(4*3)+(3*7)+(2*2)+(1*2)=136
136 % 10 = 6
So 146537-22-6 is a valid CAS Registry Number.

Regioselective Synthesis of 2-Arylindoles via Palladium-Catalyzed Cyclization of Phenylglyoxal and 2-Anilinoacetophenones with Anilines

Benitez-Medina, G. Eliad,Ortiz-Soto, Sofía,Cabrera, Armando,Amézquita-Valencia, Manuel

, p. 3763 - 3770 (2019/06/24)

A versatile route has been developed for the synthesis of 2-arylindoles using a Pd-catalyzed tandem process. Under reductive conditions, different 2-arylindoles were synthesized from phenylglyoxal and aniline. This synthetic methodology involves a tandem reaction of four steps with high regioselectivity. Alternatively, 2-anilinoacetophenones intermediates also can be using to give access to the corresponding 2-arylindoles.
