74405-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74405-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,0 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74405-44:
(7*7)+(6*4)+(5*4)+(4*0)+(3*5)+(2*4)+(1*4)=120
120 % 10 = 0
So 74405-44-0 is a valid CAS Registry Number.

SYNTHESIS OF OLIGODEOXYNUCLEOTIDES AND OLIGODEOXYNUCLEOTIDE ANALOGS USING PHOSPHORAMIDITE INTERMEDIATES
Dorman, M.A.,Noble, S.A.,McBride, L.J.,Caruthers, M.H.
, p. 95 - 102 (2007/10/02)
The synthesis of two deoxyoligonucleotides, d(G-T-G-A-G-T-T-A-G-C-T-C-A-C) and d(G-T-G-A-G-C-T-A-A-C-T-C-A-C), corresponding to the DNA binding site for cyclic AMP receptor protein is reported.These syntheses have been completed in milligram quantities using a silica gel polymer support methodology and mononucleotide phosphoramidites.Procedures are also reported for synthesizing diastereoisomers of dinucleoside methylphosphonate 3'-phosphoramidites.
