Check Digit Verification of cas no

The CAS Registry Mumber 21399-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,9 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21399-28:
(7*2)+(6*1)+(5*3)+(4*9)+(3*9)+(2*2)+(1*8)=110
110 % 10 = 0
So 21399-28-0 is a valid CAS Registry Number.

Thiazine-2-Thiones as masked 1-Azadienes in cascade dimerization reactions

Kruithof, Art,Velde, Christophe M. L. Vande,Ruijter, Eelco,Orru, Romano V. A.

, (2017)

We report the unexpected formation of a 1-Azadiene dimer from 4,6-diphenyl-3,6-dihydro- 2H-1,3-Thiazine-2-Thiones under prolonged microwave irradiation. In this manner, thiazine-2-Thiones act as masked 1-Azadiene equivalents, which makes them useful synthetic tools to access complex heterocyclic frameworks. We compare this dimerization with earlier approaches and elaborate on the observed diastereoselectivity.

Alkaline-earth phosphonate MOFs with reversible hydration-dependent fluorescence

Fard,Kalinovskyy,Spasyuk,Blight,Shimizu

, p. 12865 - 12868 (2016)

A new rigid tritopic phosphonic ligand, 2,4,6-tris(4-phosphonophenyl)pyridine (H6L), was synthesized and used to assemble isostructural barium (1) and strontium (2) phosphonate metal organic frameworks that exhibit fully reversible and selective water-dependent fluorescence red-shift at room temperature.

Strategic design of triphenylamine- and triphenyltriazine-based two-dimensional covalent organic frameworks for CO2 uptake and energy storage

El-Mahdy, Ahmed F. M.,Kuo, Cheng-Han,Alshehri, Abdulmohsen,Young, Christine,Yamauchi, Yusuke,Kim, Jeonghun,Kuo, Shiao-Wei

, p. 19532 - 19541 (2018/10/24)

Hexagonally ordered covalent organic frameworks (COFs) are interesting new crystalline porous materials that have massive potential for application in gas storage. Herein, we report the synthesis of two series of two-dimensional hexagonally ordered COFs - TPA-COFs and TPT-COFs - through one-pot polycondensations of tris(4-aminophenyl)amine (TPA-3NH2) and 2,4,6-tris(4-aminophenyl)triazine (TPT-3NH2), respectively, with triarylaldehydes featuring different degrees of planarity, symmetry, and nitrogen content. All the synthesized COFs exhibited high crystallinity, large BET surface areas (up to 1747 m2 g-1), excellent thermal stability, and pore size distributions from 1.80 to 2.55 nm. The symmetry and planarity of the monomers strongly affected the degrees of crystallinity and the BET surface areas of the resultant COFs. In addition, these COFs displayed excellent CO2 uptake efficiencies of up to 65.65 and 92.38 mg g-1 at 298 and 273 K, respectively. The incorporation of the more planar and higher-nitrogen-content triaryltriazine unit into the backbones of the TPA-COFs and TPT-COFs enhanced the interactions with CO2, leading to higher CO2 uptakes. Moreover, the synthesized COFs exhibited electrochemical properties because of their conjugated structures containing redox-active triphenylamine groups. This study exposes the importance of considering the symmetry and planarity of the monomers when designing highly crystalline COFs; indeed, the structures of COFs can be tailored to vary their functionalities for specific applications.
