Calculate Digit Verification of CAS Registry Number 1450818-55:
(9*1)+(8*4)+(7*5)+(6*0)+(5*8)+(4*1)+(3*8)+(2*5)+(1*5)=159
159 % 10 = 9
So 1450818-55-9 is a valid CAS Registry Number.

Stereoselective synthesis of 4-aminobenzo[: C] [1,2]thiazine via modification of the Harmata benzothiazine synthesis

Battula,Subbareddy,Chakravarthy,Saravanan

, p. 55710 - 55714 (2016/07/06)

A stereoselective synthesis of 4-aminobenzothiazines was developed through a modified Harmata benzothiazine synthesis. The reaction has very good substrate scope and good functional group tolerance was observed. The products were obtained with high enantiomeric purity. Many interesting heterocyclic analogues were made using this methodology.
