Check Digit Verification of cas no

The CAS Registry Mumber 894104-78-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,4,1,0 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 894104-78:
(8*8)+(7*9)+(6*4)+(5*1)+(4*0)+(3*4)+(2*7)+(1*8)=190
190 % 10 = 0
So 894104-78-0 is a valid CAS Registry Number.

Size-Selective Binding of Sodium and Potassium Ions in Nanoporous Thin Films of Polymerized Liquid Crystals

B?gels, Gerardus M.,Lugger, Jody A. M.,Goor, Olga J. G. M.,Sijbesma, Rint P.

, p. 8023 - 8030 (2016)

The development of a nanoporous material from a columnar liquid crystalline complex between a polymerizable benzoic acid derivative and a 1,3,5-tris(1H-benzo[d]imidazol-2-yl)benzene template molecule is described. The morphology of the liquid crystalline complex is retained upon polymerization and quantitative removal of the template molecule affords a nanoporous material with the same lattice parameters. The nanoporous material selectively binds cations from aqueous solution, with selectivity for sodium and potassium ions over lithium and barium ions, as shown with FT-IR. Binding is also quantified gravimetrically with a quartz crystal microbalance with dissipation monitoring, a technique that is used for this purpose for the first time here.

Cyclic tetramer of a metalloporphyrin based on a quadruple hydrogen bond

Ohkawa, Haruki,Takayama, Akihiro,Nakajima, Satoshi,Nishide, Hiroyuki

, p. 2225 - 2228 (2007/10/03)

This paper describes the selective formation of a cyclic tetramer from a readily synthesized metalloporphyrin with two self-complementary quadruple hydrogen-bonding units. The extremely strong quadruple hydrogen-bonding unit, 2-ureido-4[1H]-pyrimidinone,
