Check Digit Verification of cas no

The CAS Registry Mumber 1118073-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,8,0,7 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1118073-63:
(9*1)+(8*1)+(7*1)+(6*8)+(5*0)+(4*7)+(3*3)+(2*6)+(1*3)=124
124 % 10 = 4
So 1118073-63-4 is a valid CAS Registry Number.

Synthesis of 1-amino-1H-indole-3-carboxylates by copper(I)-catalyzed intramolecular amination of aryl bromides

Melkonyan, Ferdinand,Topolyan, Artyom,Yurovskaya, Marina,Karchava, Alexander

, p. 5952 - 5956 (2008)

A simple route to various N-substituted 1-amino-1H-indole-3-carboxylates by use of copper(I)-catalyzed intramolecular N-arylation has been established. For the preparation of N-monosubstituted and N-unsubstituted derivatives, the cyclization of Boc-protected enehydrazines and subsequent deprotection were applied. Furthermore, 1-alkoxyindole-3-carboxylates can be synthesized by use of the same protocol Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
