1209456-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1209456-80-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,9,4,5 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1209456-80:
(9*1)+(8*2)+(7*0)+(6*9)+(5*4)+(4*5)+(3*6)+(2*8)+(1*0)=153
153 % 10 = 3
So 1209456-80-3 is a valid CAS Registry Number.

Enzymatic acylation of nucleosides-Novel route to nucleopeptides
Sergeev, Maxim E.,Voyushina, Tatiana L.
experimental part, p. 104 - 106 (2010/10/03)
An efficient and straightforward proteolytic enzyme-catalyzed approach towards the regioselective synthesis of nucleopeptides was developed. Appropriate reaction conditions were investigated and certain peptide-modified nucleosides were obtained with 70-9
