Check Digit Verification of cas no

The CAS Registry Mumber 73343-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,4 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73343-44:
(7*7)+(6*3)+(5*3)+(4*4)+(3*3)+(2*4)+(1*4)=119
119 % 10 = 9
So 73343-44-9 is a valid CAS Registry Number.

Synthesis and anti-inflammatory activity of 2,3-diaryl-4(3H)-quinazolinones

Yadav,Shirude,Parmar,Balaraman,Giridhar

, p. 1038 - 1045 (2008/09/16)

2,3-Diaryl-4(3H)-quinazolinones containing various substituents on diaryl rings have been synthesized and evaluated for their cyclooxygenase-2 inhibitory activity by the colorimetric COX (ovine) inhibitor screening assay and anti-inflammatory activity by the carrageenan-induced rat paw edema assay. 2-(4-Nitrophenyl)-3-(4-tolyl)-4(3H)-quinazolinone showed a maximum COX-2 inhibition of 27.72% at 22 μM concentration in the present series and exhibited a mild anti-inflammatory activity at a dose of 50 mg/kg in carrageenan-induced rat paw edema assay.
