Check Digit Verification of cas no

The CAS Registry Mumber 161109-94-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,0 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161109-94:
(8*1)+(7*6)+(6*1)+(5*1)+(4*0)+(3*9)+(2*9)+(1*4)=110
110 % 10 = 0
So 161109-94-0 is a valid CAS Registry Number.

Nucleosides. LVI. Synthesis and chemical modifications of 3'-deoxy- pyrimidine nucleosides

Rhie,Pfleiderer

, p. 1425 - 1452 (2007/10/02)

3'-Deoxyuridine(1) and 3'-deoxycytidine(2) were prepared with improved yields by two different methods applying either the Barton procedure to appropriate 2',5'-di-O-protected pyrimidine nucleosides or by choosing the direct glycosylation of the pyrimidine bases with 1,2-di-O-acetyl-5-O- toluoyl-3-deoxy-D-erythro-pentofuranose via the silylation approach. Suitable protecting groups for the sugar moiety have been found in the trityl, tert- butyldimethylsilyl and the thexyl groups which are inert in the radical deoxygenation process. The newly synthesised compounds were characterized by elemental analyses and UV and 1H-NMR spectra.
