391868-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 391868-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,8,6 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 391868-13:
(8*3)+(7*9)+(6*1)+(5*8)+(4*6)+(3*8)+(2*1)+(1*3)=186
186 % 10 = 6
So 391868-13-6 is a valid CAS Registry Number.

Microwave promoted environmentally benign synthesis of 2- aminobenzothiazoles and their urea derivatives

Li, Zheng,Xiao, Shuxiu,Tian, Guoqiang,Zhu, Anguo,Feng, Xu,Liu, Jing

experimental part, p. 1124 - 1133 (2009/04/06)

2-Aminobenzothiazoles were efficiently synthesized using stable, crystalline tetrabutylammonium tribromide instead of toxic, corrosive liquid bromine under solvent-free and microwave irradiation condition. Furthermore, benzothiazol-2-ylureas were synthesized in good to high yield by reactions of 2-aminobenzothiazoles with N-trichloroacetanilides, which were used as a substitute for toxic, unstable isocyanates, under microwave irradiation condition. This protocol has advantages of no utilization of hazardous chemicals, rapid reaction rate, high yield, and easy work-up procedure. Copyright Taylor & Francis Group, LLC.
