Check Digit Verification of cas no

The CAS Registry Mumber 220693-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,9 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220693-38:
(8*2)+(7*2)+(6*0)+(5*6)+(4*9)+(3*3)+(2*3)+(1*8)=119
119 % 10 = 9
So 220693-38-9 is a valid CAS Registry Number.

Zidampidine, an aryl phosphate derivative of AZT: In vivo pharmacokinetics, metabolism, toxicity, and anti-viral efficacy against hemorrhagic fever caused by Lassa virus

Uckun,Venkatachalam,Erbeck,Chen,Petkevich,Vassilev

, p. 3279 - 3288 (2005)

The pharmacokinetics, metabolism, and toxicity of Zidampidine, an aryl phosphate derivative of AZT, 3′-azidothymidine-5′-[p-bromophenyl methoxyalaninyl phosphate] were investigated in CD-1 mice. Following iv injection, Zidampidine was rapidly converted to

Aryl phosphate derivatives of d4T having anti-HIV activity

-

Page column 15-16, (2008/06/13)

Aryl phosphate derivatives of d4T with para-bromo substitution on the aryl group show markedly increased potency as anti-HIV agents without undesirable levels of cytotoxic activity. In particular, these derivatives are potent inhibitors of HIV reverse transcriptase. In a preferred aspect of the present invention, the phosphorus of the aryl phosphate group is further substituted with an amino acid residue that may be esterified or substituted, such as a methoxy alaninyl group.
