Check Digit Verification of cas no

The CAS Registry Mumber 1268700-07-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,7,0 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1268700-07:
(9*1)+(8*2)+(7*6)+(6*8)+(5*7)+(4*0)+(3*0)+(2*0)+(1*7)=157
157 % 10 = 7
So 1268700-07-7 is a valid CAS Registry Number.

New synthesis of 2-aroylbenzothiazolesviametal-free domino transformations of anilines, acetophenones, and elemental sulfur

Doan, Khang V.,Doan, Son H.,Huynh, Tien V.,Luong, Ngoc T. K.,Nguyen, Duyen T. P.,Nguyen, Tung T.,Phan, Nam T. S.

, p. 18423 - 18433 (2020/06/08)

A new synthesis of 2-aroylbenzothiazolesviaiodine-promoted domino transformations of anilines, acetophenones, and elemental sulfur was demonstrated. The highlights of this tandem synthesis are (1) easily available anilines and acetophenones as feedstock;

Synthesis of 2-Acylbenzothiazoles via the Cu(OTf)2-Catalyzed tandem reaction of β,β-Dihalidestyrenes with 2,2′- Disulfanediyldianilines

Zhou, Zeng-Le,Fang, Tao,Tang, Ri-Yuan,Zhang, Xing-Guo,Deng, Chen-Liang

supporting information, p. 255 - 260 (2014/02/14)

A new method has been developed for the one-pot construction of 2-acylbenzothiazoles via the Cu(OTf)2-catalyzed tandem reaction of β,β-dihalidestyrenes with 2,2′-disulfane-diyldianilines. A variety of different dihalidestyrenes and diphenyldisulfanes were efficiently converted into the corresponding 2-acylbenzothiszole derivatives in the presence of Cu(OTf)2. Most importantly, this protocol allowed for the long chain 1,1-dibromohept-1-ene to be converted into the corresponding 2-hexylbenzo[d]thiazole in moderate yield.

Rucl33h2o catalyzed tandem reaction of alkynylbromides with 2-aminothiophenols in water: A convenient synthesis of 2-benzoylbenzothiazoles

Fan, Xuesen,He, Yan,Guo, Shenghai,Zhang, Xinying

experimental part, p. 1568 - 1573 (2012/01/14)

RuCl33H2O catalyzed tandem reaction of alkynyl bromides with 2-aminothiophenols mediated by water is shown to represent a convenient synthesis of 2-benzoylbenzothiazoles. In addition, the Ru(iii) catalyst could be readily recovered and efficiently reused together with water up to three times. CSIRO 2011.
