75776-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75776-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,7 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75776-19:
(7*7)+(6*5)+(5*7)+(4*7)+(3*6)+(2*1)+(1*9)=171
171 % 10 = 1
So 75776-19-1 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.
