77198-43-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77198-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77198-43:
(7*7)+(6*7)+(5*1)+(4*9)+(3*8)+(2*4)+(1*3)=167
167 % 10 = 7
So 77198-43-7 is a valid CAS Registry Number.

A task-specific biodegradable ionic liquid: a novel catalyst for synthesis of bicyclic ortho-aminocarbonitriles

Gaikwad,Undale,Patil,Patravale,Kamble

, p. 1175 - 1180 (2018/05/22)

Abstract: Herein, we report a novel method for synthesis of bicyclic ortho-aminocarbonitriles catalyzed by biodegradable ionic liquid. The biodegradability (BOD analysis) of all the ionic liquids that are used to carry out the reaction is studied, and the

Multicomponent domino reactions in deep eutectic solvent: An efficient strategy to synthesize multisubstituted cyclohexa-1,3-dienamines

Azizi, Najmedin,Ahooie, Tahereh Soleymani,Hashemi, Mohammad Mahmoudi

, p. 221 - 224 (2017/09/28)

The multicomponent domino reactions of ketones, aldehydes and malononitrile in a deep eutectic solvent (DES) were developed. Urea-choline chloride based DES is effective dual solvents/organocatalysts and affording a series of multisubstituted cyclohexa-1,
