Check Digit Verification of cas no

The CAS Registry Mumber 144288-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,8 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144288-40:
(8*1)+(7*4)+(6*4)+(5*2)+(4*8)+(3*8)+(2*4)+(1*0)=134
134 % 10 = 4
So 144288-40-4 is a valid CAS Registry Number.

Synthesis of new pteridines as hypouricemic agents

Ferrand,Dumas,Decerprit

, p. 309 - 320 (2007/10/02)

A series of new pteridines and 3,4-dihydropteridines with substitution in position 2, showed a hypouricemic activity in rats. After a single oral administration in this species, the hypouricemic effect of 2-(methoxymethoxymethyl)-3,4-dihydropteridine maleate 26b and 2-(2,2,2-trifluoroethoxymethyl)-3,4-dihydropteridine maleate 32b is as potent as that of 1H-pyrazolo[3,4-d]pyrimidin-4-ol (allopurinol). We showed a long-lasting fall of uricemia in further investigation of compound 26b; this fall can reach 80%. Compound 26b, unlike allopurinol, is not an in vitro xanthine oxidase inhibitor, but the ex vivo inhibition could be proved. It could be useful in the treatment of fout in human beings.
