89720-98-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89720-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89720-98:
(7*8)+(6*9)+(5*7)+(4*2)+(3*0)+(2*9)+(1*8)=179
179 % 10 = 9
So 89720-98-9 is a valid CAS Registry Number.

Regioselective reactions of o-aminothiophenol with unsymmetrical maleic anhydrides

Balasubramaniyan, V.,Balasubramaniyan, P.,Shaikh, A. S.,Argade, N. P.

, p. 123 - 125 (2007/10/02)

Maleic anhydride (MA; Ia) and its methyl (MMA; Ib), dimethyl (DMMa; Ic), phenyl (PMA; Id) and phenylmethyl (PMMA; Ie) derivatives react with o-aminothiophenol (o-ATP) to yield benzothiazines (IIIa-e) via Michael-type addition.In contrast, its oxygenated derivatives react with o-ATP to furnish benzothiazoles (IVf-h) apparently by a different pathway.
