Check Digit Verification of cas no
The CAS Registry Mumber 67733-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,3 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67733-57:
(7*6)+(6*7)+(5*7)+(4*3)+(3*3)+(2*5)+(1*7)=157
157 % 10 = 7
So 67733-57-7 is a valid CAS Registry Number.

FORMATION OF HETEROCYCLIC HAZARDOUS COMPOUNDS BY THERMAL DEGRADATION OF ORGANIC COMPOUNDS
Bieniek, Dieter,Bahadir, Muefit,Korte, Friedhelm
, p. 719 - 722 (2007/10/02)
2,3,7,8-Tetrabromodibenzofuran in ppm concentrations can be generated via reductive debromination and subsequent intramolecular cyclization during thermolysis of polybrominated aromatic compounds such as decabromodiphenyl ethers which are used as flame retardants in plastics.The respective tetrabromobenzodioxin isomer is produced in moderate amounts.In analogy to the chlorinated isomers the formation of toxic substances from incineration or fire accident constitutes a potential hazard.
