68223-16-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68223-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,2 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68223-16:
(7*6)+(6*8)+(5*2)+(4*2)+(3*3)+(2*1)+(1*6)=125
125 % 10 = 5
So 68223-16-5 is a valid CAS Registry Number.

Chemoselective hydrogenation of nitrobenzyl ethers to aminobenzyl ethers catalyzed by palladium-nickel bimetallic nanoparticles

Chen, Wenwen,Bao, Hailin,Wang, Dingsheng,Wang, Xinyan,Li, Yadong,Hu, Yuefei

, p. 9240 - 9244 (2015/11/27)

A highly efficient and chemoselective hydrogenation of nitrobenzyl ethers to aminobenzyl ethers was developed by using a novel palladium-nickel bimetallic nanocatalyst. Since the catalytic selectivity was resulted from the synergistic effects between two metals rather than the traditional catalyst poisons, the hydrogenation proceeded smoothly under additive-free conditions. Thus, the work-up procedure was as simple as to recover the catalyst by a magnetic separation and then to evaporate the solvent.
