Check Digit Verification of cas no

The CAS Registry Mumber 1338725-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,7,2 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1338725-91:
(9*1)+(8*3)+(7*3)+(6*8)+(5*7)+(4*2)+(3*5)+(2*9)+(1*1)=179
179 % 10 = 9
So 1338725-91-9 is a valid CAS Registry Number.

One-pot approach for the synthesis of 2-aryl benzothiazoles via a two-component coupling of gem-dibromomethylarenes and o-aminothiophenols

Siddappa, Chandrappa,Kambappa, Vinaya,Umashankara, Muddegowda,Rangappa, Kanchugarakoppal S.

experimental part, p. 5474 - 5477 (2011/11/04)

One-pot synthesis of 2-aryl benzothiazoles from gem-dibromomethylarenes using 2-aminoarylthiols is described. Benzothiazoles were obtained in high chemical yields under mild conditions. This transformation would facilitate synthesis by short reaction times, large-scale synthesis, easy and quick isolation of the products, which are the main advantages of this procedure.
