Check Digit Verification of cas no

The CAS Registry Mumber 1268700-09-9 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 1268700-09:
(9*1)+(8*2)+(7*6)+(6*8)+(5*7)+(4*0)+(3*0)+(2*0)+(1*9)=159
159 % 10 = 9
So 1268700-09-9 is a valid CAS Registry Number.

Iron-catalyzed arylation or aroylation of benzothiazoles with benzylic alcohols and aryl ketones

Wang, Jian,Zhang, Xiao-Zhuan,Chen, Shan-Yong,Yu, Xiao-Qi

supporting information, p. 245 - 250 (2014/01/06)

An iron-catalyzed arylation or aroylation of benzothiazoles with alcohols and aryl ketones via an in situ cross-trapping strategy has been described. Both the use of an iron catalyst and the ratio of substrates are important for this transformation, and this reaction is sensitive to the electronic effects of the substituents.

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.
