Check Digit Verification of cas no

The CAS Registry Mumber 21226-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,2 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21226-24:
(7*2)+(6*1)+(5*2)+(4*2)+(3*6)+(2*2)+(1*4)=64
64 % 10 = 4
So 21226-24-4 is a valid CAS Registry Number.

Sequential C-S and S-N Coupling Approach to Sulfonamides

Chen, Kai,Chen, Wei,Han, Bing,Chen, Wanzhi,Liu, Miaochang,Wu, Huayue

supporting information, p. 1841 - 1845 (2020/03/04)

A one-pot three-component reaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.

Metal-free direct construction of sulfonamides via iodine- mediated coupling reaction of sodium sulfinates and amines at room temperature

Wei, Wei,Liu, Chunli,Yang, Daoshan,Wen, Jiangwei,You, Jinmao,Wang, Hua

supporting information, p. 987 - 992 (2015/03/30)

A simple, practical, and metal-free protocol has been developed for the synthesis of sulfonamides from sodium sulfinates and various amines through an iodine-mediated SN bond formation reaction at room temperature. This green reaction is cost-effective, operationally straightforward, and especially proceeds under very mild conditions to afford the target products in good to excellent yields (up to 98%).

UFU ('Ullmann-Finkelstein-Ullmann'): a new multicomponent reaction

Toto, Patrick,Gesquière, Jean-Claude,Cousaert, Nicolas,Deprez, Benoit,Willand, Nicolas

, p. 4973 - 4978 (2007/10/03)

We developed conditions to carry out the first 'one-pot' Ullmann-Finkelstein-Ullmann multicomponent reaction reported. This reaction allows the one-pot synthesis of dissymmetrical para-disubstituted benzene scaffold from 1-bromo-4-iodobenzene and two N-nu
