Check Digit Verification of cas no

The CAS Registry Mumber 1616883-32-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,8,8 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1616883-32:
(9*1)+(8*6)+(7*1)+(6*6)+(5*8)+(4*8)+(3*3)+(2*3)+(1*2)=189
189 % 10 = 9
So 1616883-32-9 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.
