134903-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134903-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134903-73:
(8*1)+(7*3)+(6*4)+(5*9)+(4*0)+(3*3)+(2*7)+(1*3)=124
124 % 10 = 4
So 134903-73-4 is a valid CAS Registry Number.

A NEW METHOD FOR THE SYNTHESIS OF N-ARYLPHTHALISOIMIDES
Guirado, Antonio,Zapata, Andres,Fenor, Manuel
, p. 2633 - 2636 (2007/10/02)
N-arylphthalisoimides have been synthesized in almost quantitative yields by the reaction, under very mild conditions, of 3,3-dichlorphthalide with aromatic amines.
