43020-58-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 43020-58-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,0,2 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 43020-58:
(7*4)+(6*3)+(5*0)+(4*2)+(3*0)+(2*5)+(1*8)=72
72 % 10 = 2
So 43020-58-2 is a valid CAS Registry Number.

Synthesis of N-phenylanthranilic acid derivatives using water as solvent in the presence of ultrasound irradiation

Docampo Palacios, Maite L.,Pellon Comdom, Rolando F.

, p. 1771 - 1775 (2007/10/03)

An improved synthesis of N-phenylanthranilic acid using water as solvent can be achieved by ultrasound irradiation. A number of N-phenylanthranilic acids were prepared in good yields in a very short reaction time.

Use of N,N-dimethylformamide as solvent in the synthesis of N-phenylanthranilic acids

Pellon, Rolando F.,Carrasco, Ramon,Marquez, Tania,Mamposo, Taimirys

, p. 5107 - 5110 (2007/10/03)

It is known that N-phenylanthranilic acids can be synthesized by Ullmann-Goldberg condensation in different conditions. This paper reports some parameters which influence the condensation and reports a general procedure for this reaction using N,N-Dimethylformamide as solvent.
