129399-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129399-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,9 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129399-13:
(8*1)+(7*2)+(6*9)+(5*3)+(4*9)+(3*9)+(2*1)+(1*3)=159
159 % 10 = 9
So 129399-13-9 is a valid CAS Registry Number.

Building blocks for oligonucleotide analogs with dimethylene-sulfide, -sulfoxide, and -sulfone groups replacing phosphodiester linkages
Schneider,Benner
, p. 335 - 338 (2007/10/02)
Routes are presented for the synthesis of 3',5'-bishomo-deoxyribonucleosides, building blocks needed to synthesize oligonucleotide analogs where the -O-PO2-O- groups are replaced by -CH2-SO2-CH2-,-CH2
