152963-78-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152963-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,9,6 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 152963-78:
(8*1)+(7*5)+(6*2)+(5*9)+(4*6)+(3*3)+(2*7)+(1*8)=155
155 % 10 = 5
So 152963-78-5 is a valid CAS Registry Number.

Synthesis of 2-fluoro sugar and its condensation reaction with silylated thymine
Niihata,Ebata,Kawakami,Matsushita
, p. 1509 - 1512 (1995)
2,3-Dideoxy-2-fluoro-D-erythro-pentofuranose was easily prepared from 3-DPA lactone. The condensation reaction between 1-O-acetyl derivative of this sugar and silylated thymine in the presence of TMSOTf proceeded in a poorly stereoselective manner.
