Check Digit Verification of cas no

The CAS Registry Mumber 1242335-31-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,3,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1242335-31:
(9*1)+(8*2)+(7*4)+(6*2)+(5*3)+(4*3)+(3*5)+(2*3)+(1*1)=114
114 % 10 = 4
So 1242335-31-4 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.

, p. 5474 - 5477 (2011)

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.
