Check Digit Verification of cas no

The CAS Registry Mumber 4440-89-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4440-89:
(6*4)+(5*4)+(4*4)+(3*0)+(2*8)+(1*9)=85
85 % 10 = 5
So 4440-89-5 is a valid CAS Registry Number.

Process for Preparing Optically Active Diphosphanes

-

Page/Page column 7, (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.
