184219-30-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 184219-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,2,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 184219-30:
(8*1)+(7*8)+(6*4)+(5*2)+(4*1)+(3*9)+(2*3)+(1*0)=135
135 % 10 = 5
So 184219-30-5 is a valid CAS Registry Number.

Synthesis of dendritic phenol ether derivatives with a naphthalene core

Xiang, Zhonghua,Cao, Derong

, p. 1318 - 1324 (2008/09/19)

A series of dendritic phenol ether derivatives with a naphthalene core were synthesized by the Williamson reaction as a coupling reaction between 1-hydroxymethylnaphthalene and polyether-based dendritic fragments in the presence of phase-transfer catalyst and alkali. The modified method for chlorination of dendritic benzyl alcohol was also developed using PPh3 and CCl4 as reagents and CH2Cl2/CCl4 as solvent. Copyright Taylor & Francis Group, LLC.

Dendritic initiators for "living" radical polymerizations: A versatile approach to the synthesis of dendritic-linear block copolymers

Leduc, Marc R.,Hawker, Craig J.,Dao, Julian,Fréchet, Jean M. J.

, p. 11111 - 11118 (2007/10/03)

The first use of polyether dendrons as macromolecular initiators for the controlled free radical polymerization of vinyl monomers has been demonstrated. Dendrons containing either a single benzylic TEMPO or halide functionality at their focal point have b
