Check Digit Verification of cas no

The CAS Registry Mumber 52204-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,0 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52204-64:
(7*5)+(6*2)+(5*2)+(4*0)+(3*4)+(2*6)+(1*4)=85
85 % 10 = 5
So 52204-64-5 is a valid CAS Registry Number.

NHC-stabilized ruthenium nanoparticles as new catalysts for the hydrogenation of aromatics

Gonzalez-Galvez, David,Lara, Patricia,Rivada-Wheelaghan, Orestes,Conejero, Salvador,Chaudret, Bruno,Philippot, Karine,Van Leeuwen, Piet W.N.M.

, p. 99 - 105 (2013/04/10)

The application of ruthenium nanoparticles (RuNPs) stabilized by the N-heterocyclic carbenes (NHC) N,N′-di(tert-butyl)imidazol-2-ylidene (ItBu) and 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene IPr as catalysts in the hydrogenation of several substrates is reported under various reaction conditions (solvent, substrate concentration, substrate/metal ratio, temperature). The RuNHC nanoparticles are active catalysts in the hydrogenation of aromatics and show an interesting ligand effect, RuIPr NPs being generally more active than RuItBu.

Ligand effect in the Rh-NP catalysed partial hydrogenation of substituted arenes

Castelbou, Jessica Llop,Gual, Aitor,Mercade, Elisabet,Claver, Carmen,Godard, Cyril

, p. 2828 - 2833 (2013/09/24)

The Rh nanoparticles Rh1-Rh4 stabilised by the mono- and bidentate phosphine and phosphite ligands I-IV were synthesised, characterised and applied as catalysts in the partial hydrogenation of substituted arenes. In the case of disubstituted arenes, selectivities for the corresponding cyclohexene derivatives of up to 39% were achieved at ca. 40% conversion. The effect of parameters such as temperature and pressure was also examined. In the hydrogenation of styrene, very high selectivities for ethylbenzene were achieved with TOF values up to ca. 23500 h-1. All these results show that the catalytic performance of small Rh-NPs can be modulated by the appropriate choice of stabilising agents.

Diphosphite ligands derived from carbohydrates as stabilizers for ruthenium nanoparticles: Promising catalytic systems in arene hydrogenation

Gual, Aitor,Axet, M. Rosa,Philippot, Karine,Chaudret, Bruno,Denicourt-Nowicki, Audrey,Roucoux, Alain,Castillon, Sergio,Claver, Carmen

experimental part, p. 2759 - 2761 (2009/02/05)

Ruthenium nanoparticles (RuNPs) were prepared through the hydrogenation of [Ru(COD)(COT)] (COD = 1,5-cyclooctadiene, COT = 1,3,5-cyclooctatriene) in the presence of diphosphites derived from carbohydrates as stabilizing agents, and interestingly, structur
