Check Digit Verification of cas no

The CAS Registry Mumber 3991-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3991-83:
(6*3)+(5*9)+(4*9)+(3*1)+(2*8)+(1*3)=121
121 % 10 = 1
So 3991-83-1 is a valid CAS Registry Number.

Benzoquinazoline inhibitors of thymidylate synthase: Enzyme inhibitory activity and cytotoxicity of some 3-amino- and 3-methylbenzo[f]quinazolin- 1(2H)-ones

Pendergast,Johnson,Dickerson,Dev,Duch,Ferone,Hall,Humphreys,Kelly,Wilson

, p. 2279 - 2291 (1993)

The synthesis and thymidylate synthase (TS) inhibitory activity of a series of simple benzo[f]-quinazolin-1(2H)-ones are described. Fully aromatic 3-amino compounds with compact lipophilic substituents in the 9-position were found to have I50 values as low as 20 nM on the isolated enzyme, and represent the first examples of potent, folate-based TS inhibitors that completely lack any structural feature corresponding to the (p- aminobenzoyl)glutamate moiety of the cofactor. A number of the compounds also showed moderate growth inhibitory activity against a human colon adenocarcinoma cell line (SW480), with IC50 values as low as 2 μM.
