1169704-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1169704-47-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,7,0 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1169704-47:
(9*1)+(8*1)+(7*6)+(6*9)+(5*7)+(4*0)+(3*4)+(2*4)+(1*7)=175
175 % 10 = 5
So 1169704-47-5 is a valid CAS Registry Number.

Resolution of pentafluorophenyl active esters using (S)-4-phenyloxazolidin- 2-thione
Shaye, Najla Al,Broughton, Tom W.,Coulbeck, Elliot,Eames, Jason
experimental part, p. 960 - 964 (2009/09/29)
A series of structurally related racemic pentafluorophenyl active esters were resolved using an equimolar amount of (S)-4- phenyloxazolidin-2-thione. The levels of diastereocontrol were found to be excellent (>86% de at -30% conversion).
