Check Digit Verification of cas no

The CAS Registry Mumber 76609-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,0 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76609-16:
(7*7)+(6*6)+(5*6)+(4*0)+(3*9)+(2*1)+(1*6)=150
150 % 10 = 0
So 76609-16-0 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.

One-pot gold-catalyzed synthesis of 3-silylethynyl indoles from unprotected o-alkynylanilines

Brand, Jonathan P.,Chevalley, Clara,Waser, Jerome

, p. 565 - 569 (2011/06/26)

The Au(III)-catalyzed cyclization of 2-alkynylanilines was combined in a one-pot procedure with the Au(I)-catalyzed C3-selective direct alkynylation of indoles using the benziodoxolone reagent TIPS-EBX to give a mild, easy and straightforward entry to 2-substituted-3-alkynylindoles. The reaction can be applied to unprotected anilines, was tolerant to functional groups and easy to carry out (RT, and requires neither an inert atmosphere nor special solvents).

SYNTHESIS AND MASS SPECTRAL STUDIES OF FLUORINE CONTAINING 5a, 7b, 12a, 14b-TETRAHYDROBISINDOLO BENZO DIFURANS

Joshi, Krishna C.,Pathak, Vijay N.,Gupta, Ragini

, p. 153 - 162 (2007/10/02)

2:1 Cycloadducts (-H2) are formed when various fluorinated 2-arylindoles are stirred with p-benzoquinone in acidic medium and are identified as dimers of the type 5a, 7b, 12a, 14b-tetrahydrobisindolo benzo difurans.All the synthesized compounds have been characterized by their analytical and spectral (IR, PMR, 19F NMR and Mass) data.
