Check Digit Verification of cas no

The CAS Registry Mumber 149819-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,8,1 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149819-53:
(8*1)+(7*4)+(6*9)+(5*8)+(4*1)+(3*9)+(2*5)+(1*3)=174
174 % 10 = 4
So 149819-53-4 is a valid CAS Registry Number.

A general approach to the synthesis of 5-S-functionalized pyrimidine nucleosides and their analogues

Kananovich, Dzmitry G.,Reino, Alli,Ilmarinen, Kaja,Roomusoks, Marko,Karelson, Mati,Lopp, Margus

, p. 5634 - 5644 (2014/07/22)

A general and efficient approach was developed for the introduction of S-functionality at the C-5 position of cytosine and uracil nucleosides and their analogues. The key step is a palladium-catalyzed C-S coupling of the corresponding 5-bromo nucleoside derivative and alkyl thiol. The butyl 3-mercaptopropionate coupling products were further converted to the corresponding disulphides, the stable precursors of 5-mercaptopyrimidine nucleosides. the Partner Organisations 2014.

Structure-Activity Relationships of β-D-(2S,5R)- and α-D-(2S,5S)-1,3-oxathiolanyl Nucleosides as Potential Anti-HIV Agents

Jeong, Lak S.,Schinazi, Raymond F.,Beach, J. Warren,Kim, Hea O.,Shanmuganathan, Kirupathevy,et al.

, p. 2627 - 2638 (2007/10/02)

The β-D-(2S,5R)- and α-D-(2S,5S)-1,3-oxathiolanylpyrimidine and -purine nucleosides with natural nucleoside configuration were synthesized and evaluated against HIV-1 in human peripheral blood mononuclear (PBM) cells.The key intermediate 14, which was uti
