192449-16-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 192449-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,4,4 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 192449-16:
(8*1)+(7*9)+(6*2)+(5*4)+(4*4)+(3*9)+(2*1)+(1*6)=154
154 % 10 = 4
So 192449-16-4 is a valid CAS Registry Number.

Process for Preparing Optically Active Diphosphanes
-
Page/Page column 9, (2008/12/07)
The present invention relates to a process for preparing optically active bisphosphinylalkanes from the correspondingly substituted, racemic 1,2-diols. The optically active bisphosphinylalkanes which can be obtained in this way are suitable as ligands for preparing chiral transition metal catalysts.
