1357295-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1357295-71-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,2,9 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1357295-71:
(9*1)+(8*3)+(7*5)+(6*7)+(5*2)+(4*9)+(3*5)+(2*7)+(1*1)=186
186 % 10 = 6
So 1357295-71-6 is a valid CAS Registry Number.

Tricyclic isoindolines by Heck cyclization
Satyanarayana, Gedu,Maier, Martin E.
, p. 1745 - 1749 (2012/03/10)
A series of 4-formyl esters 8a-d was prepared by Michael addition of an enamine with ethyl acrylate. A subsequent condensation with 2-bromobenzylamines 3 gave rise to cyclic enamides 9aa-dd. In a Heck cyclization reaction tricyclic isoindoles 10aa-dd were formed in good yields.
