Check Digit Verification of cas no

The CAS Registry Mumber 1431767-74-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,7,6 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1431767-74:
(9*1)+(8*4)+(7*3)+(6*1)+(5*7)+(4*6)+(3*7)+(2*7)+(1*4)=166
166 % 10 = 6
So 1431767-74-6 is a valid CAS Registry Number.

Synthesis of the indoloazocine derivatives from a chiral indol amide-stabilized sulfur ylide

Juárez-Calderón, Maira,Aparicio, David M.,Gnecco, Dino,Juárez, Jorge R.,Orea, Laura,Mendoza, Angel,Sartillo-Piscil, Fernando,Del Olmo, Esther,Terán, Joel L.

, p. 2729 - 2732 (2013/06/26)

We present here a synthetic route for the access to a series of diverse indoloazocine derivatives through selective epoxidation of chiral sulfonium salt 4, which reacts with diverse aromatic and aliphatic aldehydes to give trans-glycidic amides, followed by an intramolecular electrophilic aromatic substitution promoted by Cu(OTf)2 giving the desired heterocyclic compound in a high chemical yield. Using this strategy, the total synthesis of (S,R)-(+)-norbalasubramide was achieved.
