Check Digit Verification of cas no

The CAS Registry Mumber 199456-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,5 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199456-65:
(8*1)+(7*9)+(6*9)+(5*4)+(4*5)+(3*6)+(2*6)+(1*5)=200
200 % 10 = 0
So 199456-65-0 is a valid CAS Registry Number.

10-Formyl-5,8,10-trideazafolic acid (10-formyl-TDAF): A potent inhibitor of glycinamide ribonucleotide transformylase

Boger, Dale L.,Haynes, Nancy-Ellen,Kitos, Paul A.,Warren, Mark S.,Ramcharan, Joseph,Marolewski, Ariane E.,Benkovic, Stephen J.

, p. 1817 - 1830 (2007/10/03)

The synthesis of 10-formyl-5,8,10-trideazafolic acid (3) as a potential inhibitor of glycinamide ribonucleotide transformylase (GAR Tfase) is reported. The target compound was prepared by a convergent synthesis utilizing the alkylation of hydrazone 5 with benzylic bromide 6 to construct the core heterocycle 7. The aldehyde 3 and related agents were evaluated as inhibitors of purN GAR Tfase and avian AICAR Tfase. Compound 3 exhibited potent inhibition of GAR Tfase with a K(i) of 0.26 ± 0.05 μM. In contrast, 3 exhibited more moderate inhibition of aminoimidazole carboxamide ribonucleotide transformylase (AICAR Tfase), with K(i) of 7.6 ± 1.5 μM.
