129491-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129491-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,9 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129491-74:
(8*1)+(7*2)+(6*9)+(5*4)+(4*9)+(3*1)+(2*7)+(1*4)=153
153 % 10 = 3
So 129491-74-3 is a valid CAS Registry Number.

Reactions of 2-Vinylindoles with Carbodienophiles: Synthetic and Mechanistic Aspects
Eitel, Manfred,Pindur, Ulf
, p. 5368 - 5374 (2007/10/02)
Reactions of selectively functionalized 2-vinylindoles with acyclic and cyclic carbodienophiles proceed with high regio- and/or stereoselectivities to furnish Diels-Alder adducts, Diels-Alder ene products, and Michael adducts.This methodology provides a c
