Check Digit Verification of cas no
The CAS Registry Mumber 950982-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,0,9,8 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 950982-69:
(8*9)+(7*5)+(6*0)+(5*9)+(4*8)+(3*2)+(2*6)+(1*9)=211
211 % 10 = 1
So 950982-69-1 is a valid CAS Registry Number.

Tunable ferrocenyl diphosphine ligands for the Ir-catalyzed enantioselective hydrogenation of N-aryl imines
Blaser, Hans-Ulrich,Buser, Hans-Peter,H?usel, Robert,Jalett, Hans-Peter,Spindler, Felix
, p. 34 - 38 (2001)
Ferrocenyl diphosphines R2PF-P(R′)2 are effective, tunable ligands for the iridium catalyzed enantioselective hydrogenation of N-aryl imines in the presence of iodide and acid promoters. Structure-activity/selectivity correlations were found for the hydrogenation of N-(2-ethyl-6-methylphenyl)-N-(1′-methoxymethyl)-ethylidene-amine (MEA-imine) and for 2,3,3-trimethylindolenine (TMI). Extremely high catalytic activity and moderate to good enantioselectivity were observed for the MEA imine using a catalyst generated in situ from [Ir(cod)Cl]2 and (R)-(S)-PPF-P(3,5-Xyl)2 (xyliphos). With the same type of catalysts, several other N-aryl imines can be hydrogenated with enantioselectivities between 31 and 96%, albeit with lower catalyst activities.
