Check Digit Verification of cas no

The CAS Registry Mumber 861573-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,5,7 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 861573-48:
(8*8)+(7*6)+(6*1)+(5*5)+(4*7)+(3*3)+(2*4)+(1*8)=190
190 % 10 = 0
So 861573-48-0 is a valid CAS Registry Number.

Benzylic C-H Azidation Using the Zhdankin Reagent and a Copper Photoredox Catalyst

Rabet, Pauline T. G.,Fumagalli, Gabriele,Boyd, Scott,Greaney, Michael F.

, p. 1646 - 1649 (2016)

An azidation method for C-N bond formation at benzylic C-H positions is described using copper-catalyzed visible light photochemistry and the Zhdankin azidoiodinane reagent. The method is applicable to a wide range of substrates bearing different functional groups and having a primary, secondary, or tertiary benzylic position, and is thought to proceed through a radical chain reaction.

Synthesis of novel pyrazoline-based bis(1,2,3-triazole) scaffolds via click chemistry

Kiran, Kothuri,Ashok, Dongamanti,Rao, Boddu Ananda,Sarasija, Madderla,Rao, Alapati Srinivas

, p. 241 - 251 (2017/05/09)

A series of novel bis(1,2,3-triazoles) derivatives 7a-m were synthesized by the 1,3-dipolar cycloaddition (click-reaction) of 1-methyl-3,5-bis(2-(prop-2-yn-1-yloxy)phenyl)-4,5-dihydro-1H-pyrazole (5) with various aralkyl azides 6a-m in the presence of sod

Copper promoted synthesis of substituted quinolines from benzylic azides and alkynes

Luo, Ching-Zong,Gandeepan, Parthasarathy,Wu, Yun-Ching,Chen, Wei-Chen,Cheng, Chien-Hong

, p. 106012 - 106018 (2015/12/30)

A novel copper promoted synthesis of substituted quinolines from various benzylic azides and internal alkynes has been demonstrated. The reaction features a broad substrate scope, high product yields and excellent regioselectivity. In contrast to the known two-step process of acid promoted [4 + 2] cycloaddition reaction and oxidation, the present methodology allows the synthesis of quinolines in a single step under neutral reaction conditions and can be applied to the synthesis of biologically active 6-chloro-2,3-dimethyl-4-phenylquinoline (antiparasitic agent) and 3,4-diphenylquinolin-2(1H)-one (p38αMAP kinase inhibitor). A plausible reaction mechanism involves rearrangement of benzylic azide to N-arylimine (Schmidt reaction) followed by intermolecular [4 + 2] cycloaddition with internal alkynes.
