649559-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 649559-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,5,5 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 649559-68:
(8*6)+(7*4)+(6*9)+(5*5)+(4*5)+(3*9)+(2*6)+(1*8)=222
222 % 10 = 2
So 649559-68-2 is a valid CAS Registry Number.

AMINE-SUBSTITUTED DIPHENYLDIPHOSPHINES

-

Page/Page column 45, (2008/06/13)

The invention relates to the 1,1'-diphenyl-2,2'-diphosphines of formulae (Ia), (Ib), having at least one amine substituent in para position to the phosphine group. These novel compounds are ligands for metal complexes that are catalysts for asymmetric addition reactions of prochiral organic compounds and whose catalytic properties can be adjusted in a substrate-specific manner via the substitution of the amino group.
