134705-53-6 Usage
General Description
1,2,6,9-tetrachlorodibenzo[b,d]thiophene is a highly chlorinated compound belonging to the class of polychlorinated dibenzo-p-dioxins (PCDDs). It consists of two benzene rings fused to a thiophene group, with chlorines substituting hydrogen atoms at positions 1, 2, 6, and 9 of the molecule. This chemical is known for its high toxicity and persistence in the environment, as well as its ability to bioaccumulate in the food chain. It is considered a hazardous environmental pollutant and is often found as a contaminant in industrial processes, particularly those involving the combustion of chlorine-containing materials. Exposure to 1,2,6,9-tetrachlorodibenzo[b,d]thiophene has been linked to a range of adverse health effects, including carcinogenicity, immunotoxicity, and reproductive toxicity. As a result, efforts are being made to limit its production and release into the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 134705-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134705-53:
(8*1)+(7*3)+(6*4)+(5*7)+(4*0)+(3*5)+(2*5)+(1*3)=116
116 % 10 = 6
So 134705-53-6 is a valid CAS Registry Number.
