15676-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 15676-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,7 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 15676-19:
(7*1)+(6*5)+(5*6)+(4*7)+(3*6)+(2*1)+(1*9)=124
124 % 10 = 4
So 15676-19-4 is a valid CAS Registry Number.

Incorporation of 2'-deoxysangivamycin in DNA duplexes: The conversion of a pyrrolo[2,3-d]pyrimidine nitrile to a carboxamide upon oligonucleotide deprotection

Seela, Frank,Zulauf, Matthias

, p. 2697 - 2709 (2007/10/03)

Oligonucleotides containing 2'-deoxysangivamycin are described. The phosphoramidite of 2'-deoxytoyocamycin was prepared and used in solid-phase synthesis. Upon deprotection the pyrrolo[2,3-d]pyrimidine nitrile residues were converted to carboxamides. Acco

NUCLEIC ACID RELATED COMPOUNDS. 42. A GENERAL PROCEDURE FOR THE EFFICIENT DEOXYGENATION OF SECONDARY ALCOHOLS. REGIOSPECIFIC AND STEREOSELECTIVE CONVERSION OF RIBONUCLEOSIDES TO 2 prime -DEOXYNUCLEOSIDES.

Robins,Wilson,Hansske

, p. 4059 - 4065 (2007/10/02)

Treatment of unhindered secondary alcohols with phenoxythiocarbonyl chloride (phenyl chlorothionocarbonate) in pyridine/dichloromethane, or in acetonitrile with 4-dimethylaminopyridine catalysis for hindered alcohols, gave clean conversion to their O-phenoxythiocarbonyl derivatives. Reductive deoxygenation of these phenyl thionocarbonate esters proceeded smoothly, using tri-n-butyltin hydride and a free radical initiator in warm toluene. Overall conversion yields ranged from 57 to 78% for the naturally occurring nucleosides, nucleoside antibiotics, and methyl beta -D-ribofuranoside.
