168772-59-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168772-59-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,7,7 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 168772-59:
(8*1)+(7*6)+(6*8)+(5*7)+(4*7)+(3*2)+(2*5)+(1*9)=186
186 % 10 = 6
So 168772-59-6 is a valid CAS Registry Number.

Synthesis of a carboxamide linked T*T dimer with an acyclic nucleoside unit and its incorporation in oligodeoxynucleotides
Larsen,Danel,Pedersen
, p. 1905 - 1912 (2007/10/02)
A T*T dimer with * representing a 2'-OCH2CH2NHC(O)-4' linkage connecting two nucleoside units was prepared by condensation of (S)-1-[2-(2- aminoethoxy)-3-(4,4'-dimethoxytrityloxy)propyl]thymine with 1,2-dideoxy-1- thyminyl-β-D-erythr
