Check Digit Verification of cas no

The CAS Registry Mumber 408509-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,5,0 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 408509-64:
(8*4)+(7*0)+(6*8)+(5*5)+(4*0)+(3*9)+(2*6)+(1*4)=148
148 % 10 = 8
So 408509-64-8 is a valid CAS Registry Number.

Asymmetric hydroamination of acrylonitrile derivatives catalyzed by Ni(II)-complexes

Fadini, Luca,Togni, Antonio

experimental part, p. 2555 - 2562 (2009/04/06)

Chiral ferrocenyl tridentate phosphine ligands were synthesized and used in asymmetric hydroamination reactions catalyzed by Ni(II)-complexes. Compounds of the type [Ni(PPP)L]2+, where L is a chloride, solvent molecule or a coordinated substrate, were isolated. The efficiency of these complexes in asymmetric catalysis was high when aliphatic or aromatic amines were reacted with electron-poor olefins, especially with acrylonitrile derivatives. This hydroamination reaction affords up to 95% enantioselectivity at -80 °C for the addition of morpholine to methacrylonitrile (69% ee at room temperature).

Aza-Michael Reactions in Ionic Liquids. A Facile Synthesis of β-Amino Compounds

Yadav,Reddy,Basak,Narsaiah

, p. 988 - 989 (2007/10/03)

Electron-deficient olefins undergo smoothly aza-Michael reactions with a wide range of amines in ionic liquids in the absence of any acid catalyst to produce the corresponding β-amino compounds in excellent yields with high 1,4-selectivity. The recovered ionic liquids can be reused in subsequent reactions without loss of activity. Owing to the high polarity of ionic liquids, the enones show enhanced reactivity thereby reducing reaction times and improving the yields significantly.
