66394-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66394-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,9 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66394-45:
(7*6)+(6*6)+(5*3)+(4*9)+(3*4)+(2*4)+(1*5)=154
154 % 10 = 4
So 66394-45-4 is a valid CAS Registry Number.

Synthesis of 4-aryl-1,5-benzodiazepine-2-carboxamides
Kurdina,Zalesov,Kozlov
, p. 1534 - 1537 (2007/10/03)
4,N-Diaryl-1,5-benzodiazepine-2-carboxamides were synthesized by acid-catalyzed reaction of (Z)-4,N-diaryl-2-hydroxy-4-oxo-2-butenamides with o-phenylenediamine or N,N′ -bis(triphenylphosphoranediyl)-o-phenylenediamine. The reaction mechanism is discussed
