Check Digit Verification of cas no

The CAS Registry Mumber 203808-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,8,0 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203808-30:
(8*2)+(7*0)+(6*3)+(5*8)+(4*0)+(3*8)+(2*3)+(1*0)=104
104 % 10 = 4
So 203808-30-4 is a valid CAS Registry Number.

Synthesis of new thieno[2,3-d]pyrimidine-2,4(1H,3H)-diones with analgesic and anti-inflammatory activities

Romeo, Giuseppe,Russo, Filippo,Caruso, Antonina,Cutuli, Vincenza,Amico-Roxas, Matilde

, p. 167 - 172 (2007/10/03)

A series of new 1,3-disubstituted thieno[2,3-d]pyrimidine-2,4(1H,3H)- diones were prepared to investigate their analgesic and anti-inflammatory properties. The analgesic and anti-inflammatory activities of synthesized compounds were investigated by the phenylquinone-induced writhing syndrome test, carrageenan rat paw oedema test and acetic acid-induced peritonitis assay. Most of the new compounds were found to be superior to mefenamic acid, as they were devoid of any ulcerogenic activity.
