5082-88-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5082-88-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,8 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5082-88:
(6*5)+(5*0)+(4*8)+(3*2)+(2*8)+(1*8)=92
92 % 10 = 2
So 5082-88-2 is a valid CAS Registry Number.

Incl34h2o-catalyzed trioxane as a new methylating agent for multi-methylated aromatics affording hexamethyl benzene

Chen, Song-Jie,Hua, Ruimao

experimental part, p. 61 - 63 (2010/08/20)

In the presence of a catalytic amount of InCl3-4H2O, trioxane was first used as the methylating agent for multi- methylated aromatic compounds such as pentamethylbenzene, 1,2,4,5-tetramethylbenzene and 1,3,5-trimethylbenzene to afford hexamethylbenzene in fair to high yields.

An efficient synthesis of diarylmethanes via InCl3*4H2O-catalyzed dehydration of electron-rich arenes with trioxane

Sun, Hong-Bin,Hua, Ruimao,Yin, Yingwu

, p. 2291 - 2294 (2007/10/03)

A facile, efficient and environmentally benign procedure for the synthesis of diarylmethanes via the reaction of arenes with trioxane catalyzed by InCl3*4H2O was developed. The reactions of aromatic compounds bearing electron-donating group proceeded smoothly affording the corresponding diarylmethanes in good to excellent yields.
