Check Digit Verification of cas no

The CAS Registry Mumber 944776-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,7,7 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 944776-24:
(8*9)+(7*4)+(6*4)+(5*7)+(4*7)+(3*6)+(2*2)+(1*4)=213
213 % 10 = 3
So 944776-24-3 is a valid CAS Registry Number.

Synthesis of 5,7-dibromotropono[c]pyrazole derivatives

Li, Yang,Gao, Wentao

, p. 2617 - 2623 (2010)

A facile synthesis of some novel 5,7-dibromotropono[c]pyrazole derivatives via the condensation reaction of 3-acetyl-5,7-dibromotropolone with aromatic hydrazines is described. All the synthesized compounds were obtained in good yields of 67-88% and their structures were characterized by IR, 1H NMR, MS, and elemental analysis. The Japan Institute of Heterocyclic Chemistry.
