134056-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134056-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134056-28:
(8*1)+(7*3)+(6*4)+(5*0)+(4*5)+(3*6)+(2*2)+(1*8)=103
103 % 10 = 3
So 134056-28-3 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
