Check Digit Verification of cas no

The CAS Registry Mumber 2840-28-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2840-28:
(6*2)+(5*8)+(4*4)+(3*0)+(2*2)+(1*8)=80
80 % 10 = 0
So 2840-28-0 is a valid CAS Registry Number.

Platinum nanoparticles onto pegylated poly(lactic acid) stereocomplex for highly selective hydrogenation of aromatic nitrocompounds to anilines

Oberhauser, Werner,Evangelisti, Claudio,Tiozzo, Cristina,Bartoli, Mattia,Frediani, Marco,Passaglia, Elisa,Rosi, Luca

, p. 50 - 58 (2017)

A stereocomplexed poly(lactic acid)-polyethyleneglycol copolymer was synthesized and successfully used as recyclable support for Pt nanoparticles, generated by the metal vapor synthesis technique. The confinement of the Pt nanoparticles were determined by thermal analysis. Hydrogenation reactions of chlorinated aromatic nitro compounds, containing other reducible functional groups, to the corresponding anilines occurred with the latter supported Pt nanoparticles in MeOH under very mild reaction conditions (i.e. 30?°C, p(H2)?=?5.0?bar). The covalently attached polyethyleneglycol polymer significantly increased the catalytic activity of the supported Pt nanoparticles compared to an analogous catalytic system which did not contain polyethyleneglycol but the same sized Pt nanoparticles.

A new class of heterogeneous platinum catalysts for the chemoselective hydrogenation of nitroarenes

Pandarus, Valerica,Ciriminna, Rosaria,Beland, Francois,Pagliaro, Mario

scheme or table, p. 1306 - 1316 (2011/06/25)

A new series of nanostructured platinum catalysts able to catalyze the selective reduction of nitroarenes has been developed. The materials, made of organosilica physically doped with nanostructured platinum(0), are stable and efficient. Reactions in general proceed with high yield and often go to completion, while the catalysts can be reused in further reaction runs. This establishes a new class of relevant solid catalysts for synthetic organic chemistry named SiliaCat Platinum-Hydrogel.

Chlorinated aromatic amines

-

, (2008/06/13)

An improvement in a process for the preparation of chlorinated aromatic amines by hydrogenation of the corresponding chlorinated nitro-aromatic compounds in the presence of a noble metal catalyst on a carbon support and in the presence of a sulfur compound, the improvement residing in that the sulfur compound is a thio-ether. Preferably the reaction is carried out in a weakly basic medium.
