65223-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65223-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,2,2 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65223-95:
(7*6)+(6*5)+(5*2)+(4*2)+(3*3)+(2*9)+(1*5)=122
122 % 10 = 2
So 65223-95-2 is a valid CAS Registry Number.

A REINVESTIGATION OF THE REACTION OF HYDRAZINE HYDRATE WITH 2-SUBSTITUTED STYRYL-4-QUINAZOLINES
Gupton, John T.,Shah, Ajit
, p. 1875 - 1884 (2007/10/02)
The reaction of hydrazine hydrate with certain 2-substituted styryl-4-quinazolones results in the formation of a novel tricyclic heterocycle and not the previously reported acyl hydrazide.A mechanistic rationale is presented.
