Check Digit Verification of cas no

The CAS Registry Mumber 1227615-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,6,1 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1227615-20:
(9*1)+(8*2)+(7*2)+(6*7)+(5*6)+(4*1)+(3*5)+(2*2)+(1*0)=134
134 % 10 = 4
So 1227615-20-4 is a valid CAS Registry Number.

Design, synthesis and evaluation of mutual prodrug of 4-biphenylacetic acid and quercetin tetramethyl ether (BPA-QTME) as gastrosparing NSAID

Madhukar, Mamta,Sawraj, Shruti,Sharma, Pritam Dev

, p. 2591 - 2596 (2010)

A novel mutual prodrug consisting of 4-biphenylacetic acid (BPA) and quercetin tetramethyl ether (QTME) has been synthesized as a gastrosparing NSAID, devoid of ulcerogenic side effects. The physicochemical properties, including aqueous solubility, partition coefficient, chemical stability and enzymatic hydrolysis of synthesized derivative have been studied to assess its prodrug potential. Its antiinflammatory, antiulcer and analgesic activities were also evaluated. The results indicated that BPA-QTME derivative is chemically stable, biolabile and possesses optimum lipophilicity. The synthesized compound also exhibited retention of antiinflammatory activity with reduced ulcerogenicity. Based on these observations, the therapeutic potential of this mutual prodrug is discussed.
