Check Digit Verification of cas no

The CAS Registry Mumber 1243257-37-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,5 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1243257-37:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*5)+(3*7)+(2*3)+(1*7)=135
135 % 10 = 5
So 1243257-37-5 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of 2-(2-aryl-morpholino-4-yl) ethyl esters of indomethacin as potential cyclooxygenase-2 (COX-2) inhibitors

Shi, Lei,Hu, Aixi,Xu, Jiangping,Jiang, Yiping

, p. 1339 - 1344 (2012/08/29)

A number of novel 2-(2-arylmorpholino-4-yl)ethyl 1-(4-chlorobenzoyl)-5- methoxy-2-methyl-1H-indol-3-acetate hydrochlorides were synthesized and tested for their cyclooxygenase (COX-1 and COX-2) inhibition properties in vitro. Many of these compounds exhibited moderate to good selective COX-2 inhibition, and subtle structural changes in the substituents on the side chain of the ester moiety altered the inhibitory properties significantly. 2-[2-(4-Butoxyphenyl) morpholino-4-yl]ethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-acetate hydrochloride (1f), showed good selective COX-2 inhibitory activity (Selective index (SI) 182), which is comparative with celecoxib (SI 214), a COX-2 inhibitor of diarylpyrazoles. While 2-[2-(2,4-dichloro-5-fluorophenyl)morpholino-4-yl] ethyl 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-acetate hydrochloride (1g), showed greater selective COX-2 inhibitory activity (SI 358) than celecoxib. Both compounds were identified as compromising derivatives in this class to reduce the side effects generated by nonsteroidal anti-inflammatory drugs (NSAIDs) indomethacin.
