Check Digit Verification of cas no

The CAS Registry Mumber 138668-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138668-26:
(8*1)+(7*3)+(6*8)+(5*6)+(4*6)+(3*8)+(2*2)+(1*6)=165
165 % 10 = 5
So 138668-26-5 is a valid CAS Registry Number.

Copper(II) coordination polymers of arylhydrazone of 1H-indene-1,3(2H)-dione linked by 4,4′-bipyridineor hexamethylenetetramine: Evaluation of catalytic activity in Henry reaction

Tiago, Gon?alo A.O.,Mahmudov, Kamran T.,Guedes da Silva, M. Fátima C.,Ribeiro, Ana P.C.,Huseynov, Fatali E.,Branco, Luís C.,Pombeiro, Armando J.L.

, p. 33 - 39 (2017/05/31)

The 1D and the 2D copper(II) coordination polymers [{Cu(κN,OO′-L)}2(μ-1κN:2κN′-bpy)2]n (1) and [{Cu(μ-1κN,OO′:2κO″-L)}2(μ-1κN:2κN′-hmt)]n (2), respectively, were synthesized from copper(II) nitrate and sodium 2-(2-(1,3-dioxo-1H-inden-2(3H)-ylidene) hydrazinyl)benzenesulfonate (NaHL), in the presence of 4,4′-bipyridine (4,4′-bpy) (for 1) or hexamethylenetetramine (hmt) (for 2). 1 and 2 are water soluble and are characterized by elemental analysis, IR spectroscopy, ESI-MS and single crystal X-ray diffraction. Depending on the neutral linkers, the dianionic ligand L2? displays tri- (in 1) or tetradentate (in 2) binding modes. The Cu2+ in 1 adopts a distorted N3O2 square-pyramid coordination environment, while in 2 it displays a distorted N2O3 trigonal bipyramid geometry. The catalytic activity of 1 and 2 was evaluated in the diastereoselective Henry reaction of nitroethane with a variety of aromatic and aliphatic aldehydes, in water and in organic solvents. β-Hydroxy nitroalkanes were obtained in high yields (up to 92%), and moderate-to-good syn/anti diastereoselectivities (up to 79:21), in water at room temperature.

Nanoporous lanthanide metal-organic frameworks as efficient heterogeneous catalysts for the Henry reaction

Karmakar, Anirban,Hazra, Susanta,Guedes Da Silva, M. Fátima C.,Paul, Anup,Pombeiro, Armando J. L.

, p. 1337 - 1349 (2016/03/01)

A series of self-assembled lanthanide coordination polymers formulated as [La(L1)2]n·1n(DMF)H·3n(DMF) (1), [Ce(L1)2]n·1n(DMF)H·2n(DMF) (2), [Sm(L1)2]n·1n(HCONH2)H·2n(HCONH2) (3), [La(L2)(HL2)(H2O)(DMF)2]n (4) and [Ce(L2)(HL2)(H2O)(DMF)2]n (5) [H2L1: 2-acetamidoterephthalic acid and H2L2: 2-benzamidoterephthalic acid] has been synthesized from the reactions of H2L1 or H2L2 with different lanthanide salts under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, X-ray single-crystal diffraction, powder X-ray diffraction, thermogravimetry and photoluminescence spectroscopy. X-ray diffraction analyses reveal that frameworks 1-3 have similar types of three-dimensional structures, composed of L12- ligands and trinuclear lanthanide nodes, in which two crystallographically independent lanthanide atoms are present. Frameworks 4 and 5 are isostructural, featuring a double chain-type one-dimensional coordination polymer which expands to 3D by means of H-bond interactions. These frameworks act as heterogeneous polymeric solid catalysts for the nitroaldol (Henry) reaction of different aldehydes with nitroalkanes, in water, and can be recycled without losing appreciable activity.
