Check Digit Verification of cas no

The CAS Registry Mumber 199733-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,3 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 199733-68:
(8*1)+(7*9)+(6*9)+(5*7)+(4*3)+(3*3)+(2*6)+(1*8)=201
201 % 10 = 1
So 199733-68-1 is a valid CAS Registry Number.

Synthesis of 3',5'-dithymidylyl-α-hydroxyphosphonate dimer building blocks for oligonucleotide synthesis - A new pro-oligonucleotide approach

Mauritz, Ralf P.,Meier, Chris,Uhlmann, Eugen

, p. 1209 - 1212 (2007/10/03)

The synthesis of the dimer building blocks 1 and 2 and their introduction into (T)15-oligonucleotides is described. The stability against 3'-exonuclease digestion (SVP) as well as the hybridization properties (T(m) values) were examined.
