Check Digit Verification of cas no
The CAS Registry Mumber 94442-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,4 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94442-22:
(7*9)+(6*4)+(5*4)+(4*4)+(3*2)+(2*2)+(1*2)=135
135 % 10 = 5
So 94442-22-5 is a valid CAS Registry Number.

Weakly-coordinated stable platinum nanocrystals
Marquardt, Dorothea,Barthel, Juri,Braun, Markus,Ganter, Christian,Janiak, Christoph
, p. 7607 - 7615 (2013/01/15)
Stable platinum nanocrystals with small diameters (1.0-2.3 nm), that are stable for a long time, with narrow size distributions were easily and reproducibly prepared without any additional stabilizers in glycol, glycerol, the ionic liquids (ILs) 1-n-butyl-3-methyl-imidazolium tetrafluoroborate [BMIm][BF4] and N-butyl-N-trimethyl-ammonium bis(trifluoromethylsulfonyl)imide [N4111][NTf2] or diphenylmethane (CH2Ph2) by thermal, photolytic or microwave assisted decomposition of the organometallic precursor methylcyclopentadienyl-trimethylplatinum(iv), (MeCp)PtMe3. Decomposition of the easily dispensible, air and moisture stable organometallic Pt(iv) precursor (MeCp)PtMe3 leads to well defined, small, crystalline and longterm stable Pt-nanoparticle (Pt-NP) dispersions without any additional surface-capping ligands. The Pt-NP/IL dispersion was shown to be a highly active catalyst (TOF 96000 h-1 at 0.0125 mol% Pt and quantitative conversion) for the biphasic hydrosilylation of phenylacetylene with triethylsilane, to the distal and proximal products triethyl(2- and1-phenylvinyl)silane.
