104684-74-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 104684-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,8 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104684-74:
(8*1)+(7*0)+(6*4)+(5*6)+(4*8)+(3*4)+(2*7)+(1*4)=124
124 % 10 = 4
So 104684-74-4 is a valid CAS Registry Number.

NUCLEOSIDE H-PHOSPHONATES. III. CHEMICAL SYNTHESIS OF OLIGODEOXYRIBONUCLEOTIDES BY THE HYDROGENPHOSPHONATE APPROACH

Garegg, Per J.,Lindh, Ingvar,Regberg, Tor,Stawinski, Jacek,Stroemberg, Roger,Henrichson, Christina

, p. 4051 - 4054 (1986)

A rapid synthesis of oligodeoxyribonucleotides on solid support is described via coupling of the deoxyribonucleoside 3'-H-phosphonates in the presence of various condensing reagents.

Solution-phase synthesis of branched DNA hybrids via H -phosphonate dimers

Singh, Arunoday,Tolev, Mariyan,Schilling, Christine I.,Braese, Stefan,Griesser, Helmut,Richert, Clemens

experimental part, p. 2718 - 2728 (2012/06/30)

A method for the solution-phase synthesis of branched oligonucleotides with tetrahedral or pseudo-octahedral geometry is described that involves the coupling of 3′-H-phosphonates of protected dinucleoside phosphates and organic core molecules. The dimer building blocks are produced by a synthesis that requires no chromatographic purification and that produces the dimer H-phosphonates in up to 44% yield in less than three days of laboratory work. A total of seven different branched hybrids were prepared, including a new hybrid of the sequence (CG)4TBA, where TBA stands for tetrakis(p- hydroxybiphenyl)adamantane that assembles into a material from micromolar aqueous solution upon addition of MgCl2.

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 (2007/10/03)

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.

A CONVENIENT AND GENERAL APPROACH TO THE SYNTHESIS OF PROPERLY PROTECTED d-NUCLEOSIDE-3'-HYDROGENPHOSPHONATES VIA PHOSPHITE INTERMEDIATES

Marugg, J. E.,Tromp, M.,Kuyl-Yeheskiely, E.,Marel, G. A. van der,Boom, J. H. van

, p. 2661 - 2664 (2007/10/02)

Evidence will be presented to show that the monofunctional phosphitylating reagents bis(N,N-di-ethylamino)chlorophosphine and salicylchlorophosphine are very effective for the preparation of 5'-O,N-protected d-nucleoside-3'-hydrogenphosphonates.
