120853-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120853-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120853-19:
(8*1)+(7*2)+(6*0)+(5*8)+(4*5)+(3*3)+(2*1)+(1*9)=102
102 % 10 = 2
So 120853-19-2 is a valid CAS Registry Number.

General Synthesis of 2'(3')-O-Aminoacyl Oligoribonucleotides. The Protection of the Guanine Moiety
Hagen, Michael D.,Chladek, Stanislav
, p. 3189 - 3195 (2007/10/02)
The chemical synthesis of 2'(3')-O-aminoacyl oligoribonucleotides requires the development of a specific blocking scheme for all nucleoside components.Herein, we describe the synthesis of guanosine synthons protected at the O6-position with the
