Check Digit Verification of cas no

The CAS Registry Mumber 1208258-68-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,8,2,5 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1208258-68:
(9*1)+(8*2)+(7*0)+(6*8)+(5*2)+(4*5)+(3*8)+(2*6)+(1*8)=147
147 % 10 = 7
So 1208258-68-7 is a valid CAS Registry Number.

Single-Step Synthesis of 3-Iodoquinolines from 2-Aminophenyl Ketones through a Regioselective (6-endo-dig) Electrophilic Cyclization

Yaragorla, Srinivasarao,Pareek, Abhishek,Dada, Ravikrishna,Saini, Pyare Lal

, p. 4600 - 4608 (2017)

A highly facile single-step synthetic approach to 3-iodoquinolines has been developed for the first time from readily available 2-aminobenzophenones and terminal alkynes. The reaction involves the nucleophilic addition of terminal alkynes to 2-aminobenzophenones followed by a regioselective iodocyclization (6-endo-dig) to furnish 2,4-disubstituted 3-iodoquinolines in high yields. In general, 2,4-diaryl-substituted products were isolated without the need for column chromatography.

Synthesis of Quinolines and Pyrido[3,2- g or 2,3- g]quinolines Catalyzed by Heterogeneous Propylphosphonium Tetrachloroindate Ionic Liquid

Azizi, Mahboobeh,Nasr-Esfahani, Mahboobeh,Mohammadpoor-Baltork, Iraj,Moghadam, Majid,Mirkhani, Valiollah,Tangestaninejad, Shahram,Kia, Reza

, p. 14743 - 14750 (2019/01/03)

This report explains an efficient method for synthesis of an array of quinolines via the reaction of 2-aminoaryl ketones with terminal and internal alkynes in the presence of propylphosphonium tetrachloroindate ionic liquid supported on nanosilica (PPInCl

Palladium-catalyzed synthesis of polysubstituted quinolines from 2-amino aromatic ketones and alkynes

Zhou, Wang,Lei, Jianhua

supporting information, p. 5583 - 5585 (2014/05/20)

A palladium-catalyzed one-pot method for the synthesis of quinolines from commercial or readily available 2-amino aromatic ketones and alkynes is reported for the first time. This transformation offers an alternative method for the synthesis of polysubstituted quinoline. the Partner Organisations 2014.
