22198-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22198-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,9 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22198-19:
(7*2)+(6*2)+(5*1)+(4*9)+(3*8)+(2*1)+(1*9)=102
102 % 10 = 2
So 22198-19-2 is a valid CAS Registry Number.

Synthesis of Imidazoles and Oxazoles via a Palladium-Catalyzed Decarboxylative Addition/Cyclization Reaction Sequence of Aromatic Carboxylic Acids with Functionalized Aliphatic Nitriles

Dai, Ling,Yu, Shuling,Lv, Ningning,Ye, Xuanzeng,Shao, Yinlin,Chen, Zhongyan,Chen, Jiuxi

supporting information, p. 5664 - 5668 (2021/08/01)

We herein report an efficient approach for the assembly of multiply substituted imidazoles and oxazoles in a single-step manner. These transformations are based on a decarboxylation addition and annulation of readily accessible aromatic carboxylic acids a

ACETONITRILE DERIVATIVE, PEST CONTROL AGENT, AND METHOD OF USING THE SAME

-

Page/Page column 85-86, (2010/11/08)

An acetonitrile derivative represented by the general formula (I): (I) (wherein A represents (VV) or (WW) B represents (XX) (YY) or (ZZ) and R represents hydrogen, C1-6 alkyl, etc. (Q1, Q2, Ar1, and Ar2 each represents phenyl, substituted phenyl, etc.; R1, R2, R3, R4, R6, R7, and R8 each represents hydrogen, C1-6 alkyl, etc.; R5 represents C1-6 alkyl, etc.; G represents NR10, etc.; W represents O, S, NR9, etc.; R9 and R10 each represents hydrogen, etc.; and n is an integer of 0-4)). The acetonitrile derivative is remarkably active in controlling pests even when used in a small dose. It is useful as an agricultural or horticultural bactericide or an animal parasite control agent.
