Check Digit Verification of cas no

The CAS Registry Mumber 40189-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40189-22:
(7*4)+(6*0)+(5*1)+(4*8)+(3*9)+(2*2)+(1*2)=98
98 % 10 = 8
So 40189-22-8 is a valid CAS Registry Number.

HYDRAmers: Design, synthesis and characterization of different generation novel Hydra-like dendrons based on multifunctionalized adamantane

Lamanna, Giuseppe,Russier, Julie,Menard-Moyon, Cecilia,Bianco, Alberto

, p. 8955 - 8957 (2011)

In this communication we present a new synthetic strategy to different generation Hydra-like dendrons based on tetrafunctionalized adamantane as a building block. The novel dendrons, which we termed HYDRAmers, possess at the periphery and at the central c

Self-assembly of giant supramolecular cubes with terpyridine ligands as vertices and metals on edges

, p. 1221 - 1226 (2014)

Self-assembly of three-dimensional (3-D) architecture using terpyridine (tpy)-based building blocks is challenging and seldom addressed due the fixed geometry (around 180°) of tpy-M(ii)-tpy (M = Ru, Fe, Zn, and Cd) connectivity. Here we describe the self-

Novel sulfonate-containing halogen-free flame-retardants: Effect of ternary and quaternary sulfonates centered on adamantane on the properties of polycarbonate composites

Zhu, Dong Yu,Guo, Jian Wei,Xian, Jia Xing,Fu, Shu Qin

, p. 39270 - 39278 (2017/08/21)

In order to find a more environmentally friendly flame retardant, we have designed a novel halogen-free flame-retardant (FR) system consisting of ternary and quaternary sulfonates centered on adamantane. They are named 1,3,5-tri(phenyl-4-sodium sulfonate)adamantane (AS3) and 1,3,5,7-tetrakis(phenyl-4-sodium sulfonate)adamantane (AS4), respectively. Both kinds of FRs were synthesized and compounded with polycarbonate (PC) to study their effects on the properties of PC composites. The results show that the new FR system can improve PC flame retardancy efficiently, and has mechanical strength advantages as well. The PC composites with only 0.1 wt% AS3 or 0.08 wt% AS4 can pass vertical burning tests (UL-94) V-0 level, with increasing the value of limiting oxygen index (LOI) to 31.2% or 32.3%. Moreover, they can maintain ideal mechanical properties compared to neat PC simultaneously. Finally, the flame retardant mechanism of this system was verified via thermal analysis, morphology and chemical structure analysis of the char residues.

From trigonal bipyramidal to platonic solids: Self-assembly and self-sorting study of terpyridine-based 3d architectures

Wang, Ming,Wang, Chao,Hao, Xin-Qi,Li, Xiaohong,Vaughn, Tyler J,Zhang, Yan-Yan,Yu, Yihua,Li, Zhong-Yu,Song, Mao-Ping,Yang, Hai-Bo,Li, Xiaopeng

supporting information, p. 10499 - 10507 (2014/08/05)

Using a series of tritopic 2,2':6',2'-terpyridine (tpy) ligands constructed on adamantane, three discrete 3D metallo-supramolecular architectures were assembled, i.e., trigonal bipyramidal, tetrahedron, and cube. The self-assembly used tritopic ligands as

Rigid C3-symmetric scaffolds based on adamantane

Pannier, Nadine,Maison, Wolfgang

body text, p. 1278 - 1284 (2009/04/07)

Efficient syntheses of rigid C3-symmetric scaffolds based on adamantane are described. The scaffolds are available in multigram quantities and have been designed for conjugation to various natural products such as carbohydrates and peptides. Th

Boron Tris(triflate) Catalyzed Adamantylation of Benzene and Toluene with 1- and 2-Haloadamantanes and Adamantanoyl Chlorides. Isomerization of Phenyl- and Tolyladamantanes

Olah, George A.,Farooq, Omar,Farnia, S. Morteza F.,Wu, An-hsiang

, p. 1516 - 1522 (2007/10/02)

Boron tris(triflate) catalyzed adamantylation of benzene and toluene was studied with isomeric 1- and 2-haloadamantanes.The alkylations give 1- and 2-phenyl- and isomeric tolyladamantanes in varying ratios.Interconversion of isomeric 2-phenyl(tolyl)adamantanes into the corresponding 1-phenyl(tolyl)adamantanes was observed through intermolecular isomerization involving adamantyl cations and adamantane, which is formed in significant amount in all the reactions.Decarbonylative alkylation of aromatics with adamantanoyl chlorides was also investigated.Adamantanoylated aromatics were formed only in very low amounts, the major product being adamantylated aromatics in accord with extensive decarbonylation of the adamantanoyl cations.The mechanism of the studies adamantylations was further substantiated by studying the boron tris(triflate) catalyzed isomerization of 1- and 2-aryladamantanes under comparable conditions.
