Check Digit Verification of cas no
The CAS Registry Mumber 55304-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,0 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 55304-77:
(7*5)+(6*5)+(5*3)+(4*0)+(3*4)+(2*7)+(1*7)=113
113 % 10 = 3
So 55304-77-3 is a valid CAS Registry Number.

Continuous process for the production of polybromopyridine compounds
-
, (2008/06/13)
A continuous process for producing a polybromopyridine compound comprises admixing a polychloropyridine compound with an anhydrous water soluble solvent in a first reaction zone to form a solution of the polychloropyridine compound. Hydrogen bromide gas is introduced into the solution while maintaining the temperature in the range of from about 70° to about 140° C. to produce a solution of the polybromopyridine compound. The solution is cooled to a temperature in the range of from about 5° to about 35° C. to precipitate the polybromopyridine compound from the anhydrous solvent. The polybromopyridine compound is separated from the anhydrous solvent and the anhydrous solvent is returned to the first reaction zone. Polybromopyridine compounds of increased purity are produced in a process having reduced material, energy and operating costs. The process does not require the use of water or other co-solvents nor the distillation of the reaction product mixture.
