885621-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 885621-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,6,2 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 885621-78:
(8*8)+(7*8)+(6*5)+(5*6)+(4*2)+(3*1)+(2*7)+(1*8)=213
213 % 10 = 3
So 885621-78-3 is a valid CAS Registry Number.

, p. 2820 - 2824 (2007/10/03)
Both L- and D-β-3′-deoxy-3′,3′-difluoronucleosides were synthesized starting from the key intermediate difluorohomoallyl alcohol 11. Deoxo-Fluor was accidentally found to be efficient in reversing the hydroxyl configuration of 34, and the desired product
