132055-17-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132055-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,0,5 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132055-17:
(8*1)+(7*3)+(6*2)+(5*0)+(4*5)+(3*5)+(2*1)+(1*7)=85
85 % 10 = 5
So 132055-17-5 is a valid CAS Registry Number.

Synthesis of 2'-(tert-butyloxycarbonyl)ribonucleosides
Losse,Suptitz
, p. 1035 - 1036 (2007/10/02)
A method for the introduction of the ter-butyloxycarbonyl-group (Boc) preferentially into the 2'-OH position of the ribonucleotides cytidine, uridine, adenosine and guanosine is described, resulting in derivatives especially applicable for ribonucleotide synthesis.
