76987-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76987-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,8 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76987-44:
(7*7)+(6*6)+(5*9)+(4*8)+(3*7)+(2*4)+(1*4)=195
195 % 10 = 5
So 76987-44-5 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
