Calculate Digit Verification of CAS Registry Number 917240-80:
(8*9)+(7*1)+(6*7)+(5*2)+(4*4)+(3*0)+(2*8)+(1*0)=163
163 % 10 = 3

Synthesis of 9-[1-(substituted)-3-(phosphonomethoxy)propyl]adenine derivatives as possible antiviral agents

Wu, Minwan,El-Kattan, Yahya,Lin, Tsu-Hsing,Ghosh, Ajit,Vadlakonda, Satish,Kotian, Pravin L.,Babu, Yarlagadda S.,Chand, Pooran

□ Acyclic N9 adenine nucleosides substituted at C-1′ position were prepared by the Mitsunobu reaction of 1-tert-butyldimethylsilyl-4- pivaloylbutan-1,2,4-triol (5) with adenine. Pivaloyl hydroxyl was modified to the phosphonomethoxy derivatives, and the tert-butyldimethylsilyl hydroxyl was converted to methoxy, azido, amino, fluoro, and α-hydroxyethyl and was eliminated to give vinyl. The resulting phosphonic acids were converted to prodrugs also. Copyright Taylor & Francis Group, LLC.
