123903-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123903-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123903-73:
(8*1)+(7*2)+(6*3)+(5*9)+(4*0)+(3*3)+(2*7)+(1*3)=111
111 % 10 = 1
So 123903-73-1 is a valid CAS Registry Number.

The preparation of (R,R)-1,3-dibenzyl-4-fluorobutane-1,2,3-triol (6) from D-isoascorbic acid and subsequent chloromethylation of this chiron made possible the synthesis of a series of 2'-deoxy-2'-fluoro-1,2'-seconucleosides. Among them were the uridine (1
