Check Digit Verification of cas no

The CAS Registry Mumber 94129-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,2 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94129-12:
(7*9)+(6*4)+(5*1)+(4*2)+(3*9)+(2*1)+(1*2)=131
131 % 10 = 1
So 94129-12-1 is a valid CAS Registry Number.

Cellulosic CuI Nanoparticles as a Heterogeneous, Recyclable Catalyst for the Borylation of α,β-Unsaturated Acceptors in Aqueous Media

Zhou, Lijie,Han, Biao,Zhang, Yaoyao,Li, Bojie,Wang, Liansheng,Wang, Jianying,Wang, Xianbao,Zhu, Lei

, p. 3220 - 3229 (2021/03/06)

Abstract: We have demonstrated that cellulosic CuI nanoparticles could perform as an efficient heterogeneous catalyst for the synthesis of useful organoboron compounds. Desired β-borylation products were all obtained in good to excellent yields under mild

Biomass waste-derived recyclable heterogeneous catalyst for aqueous aldol reaction and depolymerization of PET waste

Khiangte, Vanlalngaihawma,Laldinpuii, Z. T.,Lalhmangaihzuala, Samson,Lalmuanpuia, Chhakchhuak,Pachuau, Zodinpuia,Vanlaldinpuia, Khiangte

, p. 19542 - 19552 (2021/11/09)

In this work, we discuss the valorization of biomass waste-derived orange peel ash (OPA) by exploring its applicability as a heterogeneous catalyst in aqueous aldol reactions and demonstrating its versatility by promoting the methanolysis of poly(ethylene terephthalate) (PET) waste. The catalyst was characterized using Fourier-transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) analysis, X-ray powder diffraction (XRD), X-ray fluorescence (XRF), energy dispersive X-ray (EDX) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and thermal gravimetric analysis (TGA) to decode its chemical composition. The aldol reactions were carried out at ambient temperature in the presence of water as a solvent. PET depolymerization was performed in an autoclave for 1 h using only 6% w/w OPA. The catalyst was recovered and reused in both the reactions for up to four successive cycles with minimal loss in the catalytic activity. The use of OPA as a cost-free, eco-friendly and effective recyclable catalyst enables a greener route for C-C bond formation and PET waste recycling.

The invention relates to a method for preparing an organoboron compound and a beta-hydroxy compound by a supported copper ion Y type molecular sieve catalyst. The method for preparing the organoboroncompound mainly comprises the following steps: the step

Traceless OH-Directed Wacker Oxidation-Elimination, an Alternative to Wittig Olefination/Aldol Condensation: One-Pot Synthesis of α,β-Unsaturated and Nonconjugated Ketones from Homoallyl Alcohols

Bethi, Venkati,Fernandes, Rodney A.

, p. 8577 - 8584 (2016/09/28)

A new method for one-pot synthesis of β-substituted and β,β-disubstituted α,β-unsaturated methyl ketones from homoallyl alcohols by sequential PdCl2/CrO3-promoted Wacker process followed by an acid-mediated dehydration reaction has been developed. Remarkably, internal homoallyl alcohols delivered regioselectively nonconjugated unsaturated carbonyl compounds under the same protocol. A new starting material-based synthesis of α,β-unsaturated and nonconjugated methyl ketones is demonstrated.

PH-Tuned modulation of 1d chain to 3d metal-organic framework: Synthesis, structure and their useful application in the heterogeneous claisen-Schmidt reaction

, p. 591 - 598 (2015/03/14)

The role of pH in the formation of metal-organic frameworks (MOFs) has been studied on magnesium-based carboxylate framework systems [Mg(Pdc)(H2O)3]n (1) and [Mg(Pdc)(H2O)]n (2) (Pdc=pyridine-2,3-dica

Investigation of proline amides and pyridinium salts as catalyst for direct aldol reactions in water

, p. 326 - 331 (2014/07/08)

The catalytic potential of chiral proline amides and pyridinium salts in the aldol condensation in water was investigated. The aldol reactions of acetone with various aromatic aldehydes were carried out in water by using proline amide derivatives and pyri

Reduced graphene oxide supported piperazine in aminocatalysis

Rodrigo, Eduardo,García Alcubilla, Beatriz,Sainz, Raquel,Fierro, J. L. García,Ferritto, Rafael,Cid, M. Belén

supporting information, p. 6270 - 6273 (2014/06/09)

Reduced graphene oxide (rGO) has been used as a support for piperazine to provide a heterogeneous bifunctional organocatalyst (rGO-NH) that is able to efficiently promote vintage organic transformations such as Knoevenagel, Michael and aldol reactions. The obtained results suggest a significant role of the support in the course of these reactions. This journal is the Partner Organisations 2014.

Aldol reactions mediated by a tetrahedral boronate

Mueller, Tobias,Djanashvili, Kristina,Arends, Isabel W.C.E.,Peters, Joop A.,Hanefeld, Ulf

supporting information, p. 361 - 363 (2013/02/23)

The base is a key factor in aldol reactions in organic media, determining the selectivity. Here, we describe a tetrahedral phenylboronate salt as a mild non-nucleophilic base that is able to catalyse the aldol reaction and significantly decrease the formation of undesired elimination products. This journal is
