28083-97-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28083-97-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,8 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28083-97:
(7*2)+(6*8)+(5*0)+(4*8)+(3*3)+(2*9)+(1*7)=128
128 % 10 = 8
So 28083-97-8 is a valid CAS Registry Number.

Transglycosylation of β-D-ribofuranosylindazoles
Boryski
, p. 77 - 89 (2007/10/02)
Irreversible, acid-catalyzed 2 → 1 transglycosylation reactions of fully acetylated β-D-ribofuranosylindazoles were studied applying HPLC analysis. Results so obtained support the intermolecular mechanism of transglycosylation via a 1,2-diglycosylindazole intermediate and are compared to those of the purine series.
