209688-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 209688-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,6,8 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 209688-45:
(8*2)+(7*0)+(6*9)+(5*6)+(4*8)+(3*8)+(2*4)+(1*5)=169
169 % 10 = 9
So 209688-45-9 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.
