140659-84-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140659-84-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,5 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 140659-84:
(8*1)+(7*4)+(6*0)+(5*6)+(4*5)+(3*9)+(2*8)+(1*4)=133
133 % 10 = 3
So 140659-84-3 is a valid CAS Registry Number.

Synthesis of 5'-phosphonate linked thymidine deoxyoligonucleotides
Kofoed, Thomas,Caruthers, Marvin H.
, p. 6457 - 6460 (2007/10/03)
5'-Deoxy-5'-phosphonothymidine was synthesized and coupled with 3'-deoxy-3'-hydroxy-methylthymidine to yield a 3'-C-O-P-5' linked thymidine dinucleotide. This dimer as its 3'-phosphoramidite was used to synthesize deoxyoligonucleotides.
