139244-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139244-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139244-40:
(8*1)+(7*3)+(6*9)+(5*2)+(4*4)+(3*4)+(2*4)+(1*0)=129
129 % 10 = 9
So 139244-40-9 is a valid CAS Registry Number.

Nucleosidyl-O-methylphosphonates: A pool of monomers for modified oligonucleotides

Rejman, Dominik,Masojidkova, Milena,Rosenberg, Ivan

, p. 1683 - 1705 (2007/10/03)

An unique set of 5′-O- and 3′-O-phosphonomethyl derivatives of four natural 2′-deoxyribonucleosides, 1-(2-deoxy-β-D-threo- pentofuranosyl)thymine, 5′-O- and 2′-O-phosphonomethyl derivatives of 1-(3-deoxy-β-D-erythro-pentofuranosyl)thymine, and 1-(3-deoxy-β-D- threo-pentofuranosyl)thymine has been synthesized as a pool of monomers for the synthesis of modified oligonucleotides. The phosphonate moiety was protected with 4-methoxy-1-oxido-2-pyridylmethyl ester group, serving also as an intramolecular catalyst in the coupling step.

Ribosylation of pyrimidine 2'-deoxynucleosides

Mikhailov, Sergey N.,De Clercq, Erik,Herdewijn, Piet

, p. 1323 - 1334 (2007/10/03)

The previously developed method for the preparation of 2'-O-D- ribofuranosyl-nucleosides is extended to ribosylation of 2'- deoxynucleosides. The scope and limitations of this reaction are discussed.
