890041-18-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 890041-18-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,0,4 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 890041-18:
(8*8)+(7*9)+(6*0)+(5*0)+(4*4)+(3*1)+(2*1)+(1*8)=156
156 % 10 = 6
So 890041-18-6 is a valid CAS Registry Number.

Synthesis and Structure of Functionalized Homo Heteracalix[2]arene[2]triazines: Effect of All Heteroatom Bridges on Macrocyclic Conformation

Liang, Dong-Dong,Wang, Mei-Xiang

, p. 3316 - 3324 (2018)

A number of unprecedented homo heteracalix[2]arene[2]triazines were synthesized by means of a fragment coupling approach. Two directional nucleophilic substitution reactions of N-Boc-protected 1,3-dihydrazobenzene with cyanuric acid chloride and 2-butoxy-

Regioselective [5,5]-sigmatropic rearrangement reactions of aryl hydrazides

Kang, Hong-Min,Lim, Young-Kwan,Shin, In-Jee,Kim, Hee-Yeon,Cho, Cheon-Gyu

, p. 2047 - 2050 (2007/10/03)

N,N′-Aryl hydrazides with substituents at the ortho or meta positions undergo highly regioselective [5,5]-sigmatropic rearrangement reactions to furnish benzidines in good to excellent isolated yields. The presence of single substituent at either the ortho or meta position provides sufficient bias, effectively suppressing the formation of diphenylene, the major byproduct of the conventional benzidine rearrangement reaction.
