656249-61-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 656249-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,2,4 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 656249-61:
(8*6)+(7*5)+(6*6)+(5*2)+(4*4)+(3*9)+(2*6)+(1*1)=185
185 % 10 = 5
So 656249-61-5 is a valid CAS Registry Number.

A solid supported reagent for internucleoside H-phosphonate linkage formation

Mohe, Nikhil,Heinonen, Petri,Sanghvi, Yogesh S.,Stroemberg, Roger

, p. 897 - 899 (2005)

A fast and convenient procedure for synthesis of dinucleoside H-phosphonates is obtained through use of the novel polystyrene supported 5-carboxy-5-methyl-2-oxo-2-chloro-1,3,2-dioxaphosphorinane reagent. Virtually quantitative H-phosphonate condensations

Mechanochemical Synthesis of Short DNA Fragments

Thorpe, James D.,O'Reilly, Daniel,Fri??i?, Tomislav,Damha, Masad J.

supporting information, p. 8857 - 8861 (2020/07/08)

We demonstrate the first mechanochemical synthesis of DNA fragments by ball milling, enabling the synthesis of oligomers of controllable sequence and length using multi-step, one-pot reactions, without bulk solvent or the need to isolate intermediates. Me

Solution-phase synthesis of phosphorothioate oligonucleotides using a solid-supported acyl chloride with H-phosphonate chemistry

Adamo, Ilaria,Dueymes, Cecile,Schoenberger, Andreas,Navarro, Aude-Emmanuelle,Meyer, Albert,Lange, Meinolf,Imbach, Jean-Louis,Link, Fritz,Morvan, Francois,Vasseur, Jean-Jacques

, p. 436 - 448 (2007/10/03)

The synthesis of oligonucleotides from dimers to a hexamer by a H-phosphonate approach in solution using solid-supported acyl chloride is reported herein. This strategy avoids the use of chromatography. The work-ups have been simplified and involve filtra
