Check Digit Verification of cas no

The CAS Registry Mumber 13481-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13481-25:
(7*1)+(6*3)+(5*4)+(4*8)+(3*1)+(2*2)+(1*5)=89
89 % 10 = 9
So 13481-25-9 is a valid CAS Registry Number.

Titanium-Based Tetrakis-2,3-[5,6-di(Substituted)pyrazino]porphyrazine: Synthesis and Characterization

Assunta Navarra, Maria,D'Acunzo, Francesca,Gentili, Patrizia,Geppi, Marco,Mancone, Carmine,Martini, Francesca,Mazzapioda, Lucia,Nardelli, Francesca,Renzi, Polyssena

, (2020)

Tetrapyrazinoporphyrazine (TPysPz) ligands and metal complexes find, generally, application as electronic materials and catalysts. Considering the limited application of Titanium (Ti), we prepared and characterized a family of ligands and Ti-based complexes of tetrakis-2,3-[5,6-di-R8-pyrazino]porphyrazine (R = H, 2-Py, Ph). UV/Vis measurements in different solvents confirm molecular aggregation, which results more pronounced in the presence of 2-pyridil and phenyl substituents on the macrocycle edge. Because of low solubility, solid state NMR was applied for structure characterization. Additional IR and MALDI-TOF were carried out to complete the characterization. Cyclic voltammetry in DMSO/Bu4NBF4 0.1 m unveiled that our Ti complexes can take part in up to five redox events. The first two quasi-reversible reductions involve Ti(IV), whereas the further to or three occur at the expense of the TPysPz macrocycle. To test the applicability of our compounds as catalytic materials, we performed a preliminary cyclic voltammetry investigation in the solid-state, which showed typical peaks of hydrogen redox reactions.

Selective gas adsorption and unique structural topology of a highly stable guest-free zeolite-type MOF material with N-rich chiral open channels

Li, Jian-Rong,Tao, Ying,Yu, Qun,Bu, Xian-He,Sakamoto, Hirotoshi,Kitagawa, Susumu

, p. 2771 - 2776 (2008)

A new multifunctional ditopic tetrazolate-based ligand, 2,3-di-1H-tetrazol-5-ylpyrazine (H2dtp) has been designed and synthesized. The solvothermal reaction of this ligand with ZnCl2 gave a robust guest-free three-dimensional zeolite-like chiral metal-organic framework (MOF) complex, [Zn(dtp)], which crystallized in chiral space group P61 and possessed chiral open channels with nitrogen-rich walls and the diameter of approximately 4.1 A. This framework presents a unique uniform etd (8,3) topology, is the first example of its type in MOFs, and exhibits high thermal stability with the decomposition temperature above 380°C and permanent porosity. It is interesting that this material is able to selectively adsorb O2 and CO2 over N2 gas, being a rare example in MOFs. In addition, C2H2 and MeOH adsorption results show that although the framework channel holds nitrogen-rich walls that may provide H-bonding sites, no N...H H-bond effect between the guest molecules and microporous surface was observed.

Silica gel an efficient catalyst for one-pot synthesis of pyrazines from ethylenediamine and 1, 2-diketones and their analogs

Chakraborty, Rakesh Ranjan,Singha, Rabindranath,Ghosh, Pranab

, p. 373 - 378 (2018/09/29)

A straightforward one-pot synthesis of pyrazines from ethylenediamine and 1, 2-diketones/ α-hydroxy ketone/α-bromo ketone under solvent-free conditions at room temperature is described. This environmentally benign process has the edge on previous methods in respect of workup procedure, ease and cost of reaction, and use and generation of hazardous substances. The catalyst is recovered, characterized, and proved to be recyclable for successive four runs examined with appreciable conversions.

Facile synthesis of hydrazine derivatives of 5H-pyrrolo[3,4-b]pyrazine and 1H-pyrrolo[3,4-b]quinoxaline

, p. 3375 - 3382 (2014/01/06)

A convenient and efficient route for the chemoselective synthesis of carbohydrazide, arenesulfonylhydrazide, and thiosemicarbazone derivatives of 5H-pyrrolo[3,4-b]pyrazine and 1H-pyrrolo[3,4-b]quinoxaline from the corresponding dinitriles and substituted hydrazines was elaborated. The synthesis of starting pyrazine-2,3-dicarbonitrile was sufficiently improved by using concentrated HCl as a catalyst. Georg Thieme Verlag Stuttgart . New York.
