Check Digit Verification of cas no

The CAS Registry Mumber 59048-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,0,4 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 59048-96:
(7*5)+(6*9)+(5*0)+(4*4)+(3*8)+(2*9)+(1*6)=153
153 % 10 = 3
So 59048-96-3 is a valid CAS Registry Number.

An efficient synthesis of benzothiazole using tetrabromomethane as a halogen bond donor catalyst

Kazi, Imran,Sekar, Govindasamy

, p. 9743 - 9756 (2019)

An efficient and mild protocol has been developed for the synthesis of 2-substituted benzothiazole under solvent- and metal-free conditions using CBr4 as the catalyst. This process involves the activation of a thioamide through halogen bond formation between the sulphur atom of the thioamide and bromine atom of the CBr4 molecule. The presence of halogen-bonding interaction between N-methylthioamides and tetrabromomethane has been demonstrated with several control experiments, spectroscopic analysis and density functional theory (DFT). This methodology has a wide substrate scope for the synthesis of both 2-alkyl and 2-aryl substituted benzothiazoles.
