Check Digit Verification of cas no
The CAS Registry Mumber 218914-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,1 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 218914-85:
(8*2)+(7*1)+(6*8)+(5*9)+(4*1)+(3*4)+(2*8)+(1*5)=153
153 % 10 = 3
So 218914-85-3 is a valid CAS Registry Number.

Synthesis of 6-fluoro-D-olivose (2,6-dideoxy-6-fluoro-D-arabino-hexopyranose)
Nieschalk, Jens,O'Hagan, David
, p. 159 - 163 (1998)
An efficient synthesis of 6-fluoro-D-olivose 5 (2,6-dideoxy-6-fluoro-D-arabino-hexopyranose) starting from D-glucose is reported. Key features of the synthesis involve the early introduction of the fluorine atom at C-6 and the Fischer reductive eliminatio
