85421-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85421-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,2 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85421-86:
(7*8)+(6*5)+(5*4)+(4*2)+(3*1)+(2*8)+(1*6)=139
139 % 10 = 9
So 85421-86-9 is a valid CAS Registry Number.

Synthesis of hypoxanthine, guanine, and 6-thiopurine nucleosides of 6-deoxy-D-allofuranose
Nelson,El Khadem,Whitten,Sesselman
, p. 1071 - 1074 (2007/10/02)
Hypoxanthine, guanine, and 6-thiopurine nucleosides of 6-deoxy-D-allofuranose have been prepared as potential antitumor agents. Thus, reaction of 6-deoxy-β-allofuranosyl bromide (1) with the trimethylsilyl derivatives of hypoxanthine and guanine afforded
