404597-17-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 404597-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,5,9 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 404597-17:
(8*4)+(7*0)+(6*4)+(5*5)+(4*9)+(3*7)+(2*1)+(1*7)=147
147 % 10 = 7
So 404597-17-7 is a valid CAS Registry Number.

Facile and regioselective synthesis of 4-fluoroalkyl-2-quinolinol
Liu, Jin-Tao,Lü, He-Jun
, p. 207 - 212 (2007/10/03)
4-Fluoroalkyl-2-quinolinols were regioselectively synthesized in moderate to high yields by acid-assisted intramolecular ring-closure reaction of the corresponding N-aryl-3-oxa-polyfluoroalkanamides prepared from 2,2-dihydropolyfluoroalkanoic acids in two
