113474-91-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113474-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,7 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113474-91:
(8*1)+(7*1)+(6*3)+(5*4)+(4*7)+(3*4)+(2*9)+(1*1)=112
112 % 10 = 2
So 113474-91-2 is a valid CAS Registry Number.

A novel palladium-catalyzed coupling of thiol esters with 1-alkynes

Tokuyama, Hidetoshi,Miyazaki, Tohru,Yokoshima, Satoshi,Fukuyama, Tohru

, p. 1512 - 1514 (2003)

A new method for synthesizing α,β-acetylenic ketones by palladium-mediated coupling of thiol esters with 1-alkynes is described. The reaction could be applied to coupling of thiol esters bearing various functional groups, such as aromatic bromides, and ke

Double gold-catalysed annulation of indoles by enynones

Heffernan, Stephen J.,Tellam, James P.,Queru, Marine E.,Silvanus, Andrew C.,Benito, David,Mahon, Mary F.,Hennessy, Alan J.,Andrews, Benjamin I.,Carbery, David R.

supporting information, p. 1149 - 1159 (2013/05/22)

The gold-catalysed double functionalisation of indoles is presented. Enynones are used to annulate indoles via a double sodium tetrachloroaurate- catalysed process involving a mixture of C-H activation and alkyne activation modes of promotion. Good yields
