Check Digit Verification of cas no

The CAS Registry Mumber 1338091-83-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,0,9 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1338091-83:
(9*1)+(8*3)+(7*3)+(6*8)+(5*0)+(4*9)+(3*1)+(2*8)+(1*3)=160
160 % 10 = 0
So 1338091-83-0 is a valid CAS Registry Number.

One-Pot Reaction between N-Tosylhydrazones and 2-Nitrobenzyl Bromide: Route to NH-Free C2-Arylindoles

Bzeih, Tourin,Zhang, Kena,Khalaf, Ali,Hachem, Ali,Alami, Mouad,Hamze, Abdallah

, p. 228 - 238 (2019)

A one-pot Barluenga coupling between N-tosylhydrazones and nitro-benzyl bromide, followed by deoxygenation of ortho-nitrostyrenes, and subsequent cyclization has been developed, providing a new way to synthesize various C2-arylindoles. This method exhibits a good substrate scope and functional group tolerance, and it allows an access to NH-free indoles, which can present a potential utility in medicinal chemistry applications.
