126938-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126938-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126938-38:
(8*1)+(7*2)+(6*6)+(5*9)+(4*3)+(3*8)+(2*3)+(1*8)=153
153 % 10 = 3
So 126938-38-3 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.
