2631-71-2 Usage
General Description
Ethanone, 1-(4-aminophenyl)-2-chloro- (9CI), also known in scientific literature as 4’-chloroacetophenone, is a specific organic compound with a molecular formula of C8H7ClNO. Its structure consists of a benzene ring that is connected by a carbon atom to a ketone functional group. As suggested by its name, the benzene ring of this compound has an amino (NH2) substituent at the fourth carbon atom, whilst a chlorine atom is present on the second carbon atom of the acetone portion. It's a compound with various applications but is most prevalently used in organic chemistry as a building block to synthesize other complex molecules. Use of this compound should be undertaken with care due to potential risks associated with exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 2631-71-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2631-71:
(6*2)+(5*6)+(4*3)+(3*1)+(2*7)+(1*1)=72
72 % 10 = 2
So 2631-71-2 is a valid CAS Registry Number.

Ultrasound promoted clay catalyzed efficient and one pot synthesis of substituted oxindoles
Dandia,Bhati,Jain,Sharma
experimental part, p. 1143 - 1147 (2012/03/10)
A simple facile, one-pot synthesis of oxindoles in reasonable purity is reported via intramolecular Friedal-Craft cyclization. Clay KSF is an inexpensive, efficient and mild catalyst for the synthesis of substituted oxindoles by the reaction of chloroacetyl chloride and various anilines under the influence of ultrasonic irradiation under solvent-free conditions. The remarkable advantages of this method are the simple experimental procedures, short reaction times, high yields of products, suitability for a wide variety of substituents, and the green aspects through the avoidance of toxic catalyst and solvents.
