76972-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76972-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76972-50:
(7*7)+(6*6)+(5*9)+(4*7)+(3*2)+(2*5)+(1*0)=174
174 % 10 = 4
So 76972-50-4 is a valid CAS Registry Number.

Synthesis and Reactions of Phthalazine Derivatives
Merchant, J. R.,Kulkarni, S. D.,Venkatesh, M. S.

Hydrazones (Ia-c) fail to undergo cyclisation under different conditions to yield phthalazines (IIa-c). o-Aroylbenzoic acids (IVa-c) on treatment with hydrazine hydrate give 4-aryl-1(2H)-phthalazinones (Va-c) which react with POCl3 to yield 4-aryl-1-chlor
