Check Digit Verification of cas no

The CAS Registry Mumber 196877-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,8,7 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 196877-21:
(8*1)+(7*9)+(6*6)+(5*8)+(4*7)+(3*7)+(2*2)+(1*1)=201
201 % 10 = 1
So 196877-21-1 is a valid CAS Registry Number.

A metal-free approach for in situ regioselective synthesis of isoxazoles via 1,3 dipolar cycloaddition reaction of nitrile oxide with propargyl bromide

, (2022/02/01)

Herein, we report a multi-component reaction (MCRs) to synthesise a range of 3-phenyl-5-(bromomethyl)isoxazoles analogues using DMF/water mixture as solvent, providing desired products in good to excellent yields. The reaction efficiently involves the 1,3-dipolar cycloaddition reaction between propargyl bromide and in situ-generated α-chloro aldoximes. The protocol proceeded well under mild metal-free conditions and showed a tolerance for a wide range of substituents. Graphical abstract: [Figure not available: see fulltext.]
