Check Digit Verification of cas no

The CAS Registry Mumber 103904-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103904-90:
(8*1)+(7*0)+(6*3)+(5*9)+(4*0)+(3*4)+(2*9)+(1*0)=101
101 % 10 = 1
So 103904-90-1 is a valid CAS Registry Number.

Synthesis and Biochemical Properties of 8-Amino-6-fluoro-9-β-D-ribofuranosyl-9H-purine

Secrist, John A.,Bennett, L. Lee,Allan, Paula W.,Rose, Lucy M.,Chang, Chi-Hsiung,Montgomery, John A.

, p. 2069 - 2074 (1986)

The synthesis and characterization of 8-amino-6-fluoro-9-β-D-ribofuranosyl-9H-purine (3a) are presented.This compound is a substrate for adenosine deaminase and adenosine kinase.In L1210 cells 3a is converted to 8-aminoinosine monophosphate (4b), apparently by the action of AMP deaminase on the monophosphate of 3a, as well as to the triphosphate derivative of 3a.Pentostatin was used to inhibit adenosine deaminase, and coformycin was used to inhibit AMP deaminase in experiments designed to delineate the metabolic fate of 3a.Pentostatin was without influence on the cytotoxicity of 3a, but coformycin potentiated the cytotoxicity.The potentiation was associated with an increased cellular concentration of phosphates of 3a and a decreased concentration of 4b.
