22100-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22100-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,0 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22100-57:
(7*2)+(6*2)+(5*1)+(4*0)+(3*0)+(2*5)+(1*7)=48
48 % 10 = 8
So 22100-57-8 is a valid CAS Registry Number.

Facile aromatic nucleophilic substitution (SNAr) reactions in ionic liquids: An electrophile-nucleophile dual activation by [Omim]Br for the reaction

Zhang, Xiao,Lu, Guo-Ping,Cai, Chun

, p. 5580 - 5585 (2016/10/21)

A facile aromatic nucleophilic substitution (SNAr) reaction in recyclable [Omim]Br under relatively mild conditions has been described. An electrophile-nucleophile dual activation by [Omim]Br is also discovered based on control experiments, 1H NMR and IR spectroscopies. This chemistry provides an efficient and metal-free approach for the generation of Caryl-X (XS, N, O) bonds, many of which are significant synthetic intermediates or drugs, making this methodology attractive to both synthetic and medicinal chemistry.
