Check Digit Verification of cas no

The CAS Registry Mumber 16155-55-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,5 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16155-55:
(7*1)+(6*6)+(5*1)+(4*5)+(3*5)+(2*5)+(1*5)=98
98 % 10 = 8
So 16155-55-8 is a valid CAS Registry Number.

Intramolecular O-arylation using nano-magnetite supported N-heterocyclic carbene-copper complex with wingtip ferrocene

Naikwade, Altafhusen,Jagadale, Megha,Kale, Dolly,Gajare, Shivanand,Bansode, Prakash,Rashinkar, Gajanan

, (2019)

Nano-magnetite supported N-heterocyclic carbene-copper complex with wingtip ferrocene has been prepared via multi-step procedure. The complex has been characterized by various analytical techniques such as fourier transform infrared (FT-IR), fourier transform Raman (FT-Raman), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) analysis. The catalytic activity of the complex has been exploited in intramolecular O-arylation of o-iodoanilides under heterogeneous conditions. The complex could be successfully recycled up to twelve consecutive cycles.

(N-heterocyclic carbene)PdCl(N-heterocyclic carboxylate) complexes: Synthesis and catalytic activities towards arylation of benzoxazoles with aryl halides

Yang, Jin

, (2018/06/26)

A series of N-heterocyclic carboxylate-stabilized N-heterocyclic carbene palladium complexes have been synthesized and fully characterized. The solid-state structures indicate that each of the palladium centers is coordinated by an N-heterocyclic carbene, a chloride and a bidentate N,O-donor N-heterocyclic carboxylate ligand. The catalytic performance of the complexes was screened and the results revealed that the complexes exhibit moderate to high catalytic activities for the direct C─H bond arylation of benzoxazoles with aryl bromides.

Synthesis of 2-arylbenzoxazoles by copper-catalyzed intramolecular oxidative C-O coupling of benzanilides

Ueda, Satoshi,Nagasawa, Hideko

supporting information; experimental part, p. 6411 - 6413 (2009/03/11)

(Chemical Equation Presented) No need for additives: A wide variety of functionalized 2-arylbenzoxazoles can be prepared with high functional-group tolerance and regioselectivity by a copper-catalyzed intramolecular oxidative C-O coupling of benzanilides. The catalytic cycle is completed by the regeneration of the copper catalyst using molecular oxygen as a terminal oxidant without the need for additives.
