Check Digit Verification of cas no

The CAS Registry Mumber 1217447-83-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,4,4 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217447-83:
(9*1)+(8*2)+(7*1)+(6*7)+(5*4)+(4*4)+(3*7)+(2*8)+(1*3)=150
150 % 10 = 0
So 1217447-83-0 is a valid CAS Registry Number.

Stereoselective synthesis of 2-deoxy-2-fluoroarabinofuranosyl-α-1- phosphate and its application to the synthesis of 2′-Deoxy-2′- fluoroarabinofuranosyl purine nucleosides by a chemo-enzymatic method

Yamada, Kohei,Matsumoto, Noritake,Hayakawa, Hiroyuki

, p. 1117 - 1130 (2009)

Stereoselective introduction of a phosphate moiety into 2-deoxy-2-fluoroarabinofuranose derivatives at the anomeric position was investigated by two methods. One involved a stereoselective hydrolysis of 1-bromo-derivative, and the consecutive phosphorylation of 2-deoxy-2-fluoro- α-D-arabinofuranose via a phosphoramidite derivative. The other method involved stereoselective α-phosphorylation of the 1-bromo-derivative at the 1-position. The resulting α-1-phosphate was utilized to prepare 2′-deoxy-2′-fluoroarabinofuranosyl purine nucleosides by an enzymatic glycosylation reaction. This chemo-enzymatic method will be applicable to the synthesis of some 2′F-araNs, and three important 2′F-araNs were actually obtained in 30-40% yields from 1,3,5-tri-O-benzoyl-2-deoxy-2- fluoro-α-D-arabinose with high purity.
