19983-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19983-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,8 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19983-28:
(7*1)+(6*9)+(5*9)+(4*8)+(3*3)+(2*2)+(1*8)=159
159 % 10 = 9
So 19983-28-9 is a valid CAS Registry Number.

Carbon tetrabromide mediated oxidative cyclocondensation of ketones and thioureas: An easy access to 2-aminothiazoles

Keshari, Twinkle,Kapoorr, Ritu,Yadav, Lal Dhar S.

supporting information, p. 5623 - 5627 (2015/09/21)

A simple, mild, and efficient one-pot method for the synthesis of substituted 2-aminothiazoles has been reported. The reaction involves the formation of sulfenyl bromide as an umpolung intermediate of nucleophilic sulfur, which is responsible for C-S bond formation leading to oxidative cyclization of ketones and thioureas to furnish the desired products. Carbon tetrabromide was used as a convenient and mild brominating reagent under basic condition at room temperature to give 2-aminothiazoles in good to excellent yields.

Synthesis and Characterization of 1,3-Bis-(2-dialkylamino-5-thiazolyl)-Substituted Squaraines and Their 2-(Dialkylamino)thiazole Precursors

Keil, D.,Hartmann, H.

, p. 979 - 984 (2007/10/02)

By condensation of squaric acid (1) with 2-(dialkylamino)-substituted thiazoles 8 a novel type of heterocyclic-substituted squaraines of the general structure 9 was prepared in moderate yield mostly.The squaraines 9 obtained are sparingly soluble in the most organic solvents and exhibit, in these solvents, narrow absorption bands in the visible range at about 620-700 nm.In dispersed form, the absorption bands of the squaraines 9 are, however, broadened and shifted into the NIR region at about 900 nm.These unique properties of the new squaraines 9 suggest the use of these dyes as spectral sensitizers for laser-driven data recording or data storage media. - Key Words: Squaraines/ Squaric acid/ Thiazoles/ Sensitizers
