Check Digit Verification of cas no

The CAS Registry Mumber 1253853-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,8,5 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1253853-28:
(9*1)+(8*2)+(7*5)+(6*3)+(5*8)+(4*5)+(3*3)+(2*2)+(1*8)=159
159 % 10 = 9
So 1253853-28-9 is a valid CAS Registry Number.

Palladium Complex Immobilized on Magnetic Nanoparticles Modified with 2-Aminopyridine Ligand: A Novel and Efficient Recoverable Nanocatalyst for C–S and C–Se Coupling Reactions

Lu, Lu,Luo, Jia,Wang, Weiqi,Xu, Xiaoqing,Zhang, Jingzheng

, (2022/01/12)

A novel, versatile and efficient magnetically recoverable palladium nanocatalyst [Fe3O4@SiO2/2-aminopyridine-Pd(II)] was fabricated via the immobilization of palladium(II) complex on the surface of magnetic nanoparticles modified with 2-aminopyridine ligand. The structure of the as-fabricated Fe3O4@SiO2/2-aminopyridine-Pd(II) nanocomposite was characterized by a series of spectroscopic techniques including FT-IR, SEM, TEM, EDX, TGA, XRD, VSM and ICP-OES techniques. The Fe3O4@SiO2/2-aminopyridine-Pd(II) nanocomposite was utilized under mild and eco-friendly conditions in C–S and C–Se coupling reactions to afford a vast variety of diaryl sulfides and diaryl selenides with good to excellent yields. This heterogeneous palladium catalyst can be magnetically separated and reused for at least 7 consecutive trials without any reduction in activity.

Herein, we report an electrochemical oxidative C(sp2)–H selenylation of activated arenes. The reaction proceeds in an undivided electrochemical cell at Pt-electrodes in the presence of KI as the supporting electrolyte, which could suffer oxidat

DMSO/iodine-catalyzed oxidative C-Se/C-S bond formation: A regioselective synthesis of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes

Saba, Sumbal,Rafique, Jamal,Braga, Antonio L.

, p. 3087 - 3098 (2016/05/24)

A convenient metal-free and solvent-free iodine-catalyzed regioselective greener protocol to access different types of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes through oxidative C-Se/C-S formation via direct C(sp2)-H bond activation was developed. The products were obtained in good to excellent yields using [O or N]-containing arenes, half equiv. of various odorless diorganyl dichalcogenides (S/Se), iodine (20 mol%) as the catalyst and 3 equiv. of DMSO as the oxidant, applying MW irradiation for 10 min.
