Check Digit Verification of cas no

The CAS Registry Mumber 201011-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,1 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 201011-40:
(8*2)+(7*0)+(6*1)+(5*0)+(4*1)+(3*1)+(2*4)+(1*0)=37
37 % 10 = 7
So 201011-40-7 is a valid CAS Registry Number.

Catalysis with gold complexes immobilised on carbon nanotubes by π-π Stacking interactions: Heterogeneous catalysis versus the boomerang effect

Vriamont, Charles,Devillers, Michel,Riant, Olivier,Hermans, Sophie

, p. 12009 - 12017 (2013)

A new pyrene-tagged gold(I) complex has been synthesised and tested as a homogeneous catalyst. First, a simple 1,6-enyne was chosen as a model substrate for cyclisation by using different solvents to optimise the reaction conditions. The non-covalent immobilisation of our pyrene-tagged gold complex onto multi-walled carbon nanotubes through π-π stacking interactions was then explored to obtain a supported homogeneous catalyst. The heterogenised catalyst and its homogeneous counterpart exhibited similar activity in a range of enyne cyclisation reactions. Bearing in mind that π-π interactions are affected by temperature and solvent polarity, the reuse and robustness of the supported homogeneous catalyst was tested to explore the scope and limitations of the recyclability of this catalyst. Under the optimised conditions, recyclability was observed by using the concept of the boomerang effect. Copyright

'Click' Dendritic phosphines: Design, synthesis, application in Suzuki coupling, and recycling by nanofiltration

Janssen, Michele,Mueller, Christian,Vogt, Dieter

supporting information; experimental part, p. 313 - 318 (2009/10/20)

A new synthetic route towards stable molecular-weight enlarged monodentate phosphine ligands via 'click' chemistry was developed. These ligands were applied in the Pd-catalyzed Suzuki-Miyaura coupling of aryl halides and phenyl boronic acid. The supported systems show very similar activities compared to the unsupported analogues. Moreover, recycling experiments by means of nanofiltration using ceramic nanofiltration membranes demonstrate that these systems can be recovered and reused efficiently.

First fluorescent photoinduced electron transfer (PET) reagent for hydroperoxides

Onoda, Maki,Uchiyama, Seiichi,Endo, Atsushi,Tokuyama, Hidetoshi,Santa, Tomofumi,Imai, Kazuhiro

, p. 1459 - 1461 (2007/10/03)

(Matrix presented) A novel fluorescent reagent for hydroperoxides, 4-(2-diphenylphosphinoethylamino)-7-nitro-2,1,3-benzoxadiazole (1), was developed on the basis of the method for designing photoinduced electron transfer (PET) reagents having a benzofurazan skeleton. Compound 1 was quantitatively reacted with hydroperoxides to give its fluorescent derivative, 2. In acetonitrile, the Φ value (0.44) of 2 was 31 times greater than that of 1. The long excitation (458 nm) and emission (520 nm) wavelengths of 2 are suitable for the determination of hydroperoxides, especially in biosamples.
