Check Digit Verification of cas no

The CAS Registry Mumber 1239357-83-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,3,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1239357-83:
(9*1)+(8*2)+(7*3)+(6*9)+(5*3)+(4*5)+(3*7)+(2*8)+(1*3)=175
175 % 10 = 5
So 1239357-83-5 is a valid CAS Registry Number.

1,5-Diarylimidazoles with strong inhibitory activity against COX-2 catalyzed PGE2 production from LPS-induced RAW 264.7 cells

Che, Haiyan,Tuyen, Truong Ngoc,Kim, Hyun Pyo,Park, Haeil

scheme or table, p. 4035 - 4037 (2010/08/06)

A series of 1,5-diarylimidazoles with 4-methylsulfonylphenyl group were prepared and evaluated for the inhibitory activities against COX-2 catalyzed PGE2 production from LPS-induced RAW 264.7 cells. Most of synthesized 1,5-diarylimidazoles exhibited strong inhibitory activities regardless of the position of the 4-methylsulfonylphenyl group. The 1,5-diarylimidazoles with a halogen atom (3c-3h, 3n-3p) gave mostly excellent inhibitory activities regardless of the position and species of the halogen atom. Whereas the 1,5-diarylimidazoles with two fluorine atoms (3k, 3l, 3r, 3s) showed rather reduced inhibitory activities.
