544710-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 544710-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,4,7,1 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 544710-52:
(8*5)+(7*4)+(6*4)+(5*7)+(4*1)+(3*0)+(2*5)+(1*2)=143
143 % 10 = 3
So 544710-52-3 is a valid CAS Registry Number.

An approach to the desulfurization of oligonucleotide phosphorothioates
Reese, Colin B.,Yan, Hongbin
, p. 2501 - 2504 (2007/10/03)
Protected oligonucleotide phosphorothioates are converted by a two-step procedure into oligonucleotides with standard phosphodiester internucleotide linkages. The remaining protecting groups are then removed by ammonolysis.
