428451-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 428451-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,8,4,5 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 428451-78:
(8*4)+(7*2)+(6*8)+(5*4)+(4*5)+(3*1)+(2*7)+(1*8)=159
159 % 10 = 9
So 428451-78-9 is a valid CAS Registry Number.

Palladium-catalyzed annulation of haloanilines and halobenzamides using norbornadiene as an acetylene synthon: A route to functionalized indolines, isoquinolinones, and indoles

Thansandote, Praew,Hulcoop, David G.,Langer, Michael,Lautens, Mark

supporting information; experimental part, p. 1673 - 1678 (2009/07/17)

A general procedure for the palladium-catalyzed annulation of substituted haloanilines with norbornadiene gives functionalized indolines in 51-98% yield. These indolines can be rapidly converted to benzenoid- substituted indoles and tricyclic indolines. Extension to the use of substituted halobenzamides gives functionalized isoquinolinones in up to 86% yield.
