157793-52-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157793-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,9 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157793-52:
(8*1)+(7*5)+(6*7)+(5*7)+(4*9)+(3*3)+(2*5)+(1*2)=177
177 % 10 = 7
So 157793-52-7 is a valid CAS Registry Number.

Use of ammonium aryl H-phosphonates in the preparation of nucleoside H-phosphonate building blocks

Ozola, Vita,Reese, Colin B.,Song, Quanlai

, p. 8621 - 8624 (1996)

Ammonium 4-methylphenyl H-phosphonate 4c was used in the conversion of 5'-0-(dimethoxy-trityl)-2'-deoxynucleoside derivatives 6 into the corresponding 3'-H-phosphonates 2, which were isolated in a high state of purity and in high yield.

, p. 31 - 37 (2007/10/03)

The reaction of nucleoside H-phosphonate monoesters with phenols in the presence of a condensing agent, followed by oxidation of the in-situ-generated aryl nucleoside H-phosphonate diesters with iodine-water or with elemental sulfur, provides a new, 'one-

Aryl H-phosphonates. Part 11. Synthetic and 31P NMR studies on the formation of aryl nucleoside H-phosphonates

, p. 3327 - 3331 (2007/10/03)

The formation of aryl H-phosphonate diesters from the corresponding nucleoside 3′-H-phosphonates and various phenols was investigated in detail using 31P NMR spectroscopy. The major reaction pathways of aryl nucleoside H-phosphonates under diff

31p NMR studies on oxidative transformations of aryl nucleoside h-phosphonate diesters

Kers, Annika,Kers, Inger,Cieslak, Jacek,Kraszewski, Adam,Stawinski, Jacek

, p. 991 - 992 (2007/10/03)

Various aspects of oxidative coupling of nucleoside aryl H-phosphonate diesters with nucleosides to produce important synthetic intermediates in the phosphotriester approach to oligonucleotide synthesis, dinucleoside aryl phosphotriesters, was investigated. Copyright
