1276027-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1276027-75-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,0,2 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1276027-75:
(9*1)+(8*2)+(7*7)+(6*6)+(5*0)+(4*2)+(3*7)+(2*7)+(1*5)=158
158 % 10 = 8
So 1276027-75-8 is a valid CAS Registry Number.

Highly efficient InBr3 catalyzed michael addition of indoles to α,β-Unsaturated Esters
Liu, Ping,Chen, Wei,Ren, Kai,Wang, Lei
experimental part, p. 2399 - 2403 (2011/09/21)
A highly efficient synthetic strategy toward Michael addition of indoles to α,β-unsaturated esters has been developed using Lewis acid InBr 3 as catalyst. The reactions generated 3-substituted indoles in high yields with excellent regio-selecti
