184773-04-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 184773-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,7,7 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 184773-04:
(8*1)+(7*8)+(6*4)+(5*7)+(4*7)+(3*3)+(2*0)+(1*4)=164
164 % 10 = 4
So 184773-04-4 is a valid CAS Registry Number.

Solid phase synthesis of oligodeoxynucleoside phosphorodithioates by a phosphotriester method using a chemoselective coupling reagent

Kehler, Jan,Pueschl, Ask,Dahl, Otto

, p. 8041 - 8044 (1996)

A phosphotriester method has been developed for solid phase synthesis of oligodeoxynucleoside phosphorodithioates. Couplings are performed by chemoselective oxygen activation of protected nucleoside dithiophosphate anions 1, 7, 8, 9 with 4-nitro-6-trifluo

Solution phase synthesis of dithymidine phosphorodithioate using new S- protecting groups in combination with a chemoselective coupling reagent (PyNOP)

Kehler, Jan,Pueschl, Ask,Dahl, Otto

, p. 23 - 32 (2007/10/03)

A method for the synthesis of O-thymidin-3'-yl S-alkyl dithiophosphate monomers 1 with different S-protecting groups has been developed. These have been used for solution phase synthesis of dithymidine phosphorodithioate by a new phosphotriester method. C
