72305-96-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72305-96-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,0 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72305-96:
(7*7)+(6*2)+(5*3)+(4*0)+(3*5)+(2*9)+(1*6)=115
115 % 10 = 5
So 72305-96-5 is a valid CAS Registry Number.

Synthesis of esters of phosphonoformic acid and their antiherpes activity

Noren,Helgstrand,Johansson,Misiorny,Stening

, p. 264 - 270 (2007/10/02)

Aliphatic and aromatic mono-, di-, and triesters of phosphonoformic (foscarnet) were synthesized. The triesters were prepared by the Michaelis-Arbuzov reaction and were hydrolyzed to di- and monoesters. The compounds were tested for antiviral activity on isolated herpes simplex virus type 1 (HSV-1) DNA polymerase, in a HSV-1 plaque reduction assay, and on a cutaneous HSV-1 infection in guinea pigs. None of the esters inhibited the activity of isolated HSV-1 polymerases. Monoesters with a free carboxylic group and diesters with an aromatic carboxylic ester function were active against the cutaneous herpesa infection. Mono- and diesters with an aromatic phosphonic ester group also showed activity in the plaque-reduction assay. However, mono- and diesters with aliphatic carboxylic ester groups were inactive in all test systems. The results show that all three acidic groups of phosphonoformic acid must be free in order to get antiviral activity at the enzyme level. However, certain esters of this acid may be biotransformed to the acid itself to give antiherpes activity.
