38380-02-8 Usage
General Description
2,2',3,4,5'-Pentachlorobiphenyl, also known as PCB 97, is one of the lesser known Polychlorinated biphenyls (PCBs), a group of man-made organic chemicals widely used in various industrial and commercial applications due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties. It is a persistent organic pollutant and potential environmental toxicant, resistant to breakdown and capable of long-term persistence in the environment and bioaccumulation in living organisms. Human exposure primarily occurs through diet, inhalation, and skin contact, potentially causing a range of adverse health effects including cancer and problems related to the immune, reproductive and nervous systems. This substance is no longer produced in most countries due to health and environmental hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 38380-02-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,3,8 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 38380-02:
(7*3)+(6*8)+(5*3)+(4*8)+(3*0)+(2*0)+(1*2)=118
118 % 10 = 8
So 38380-02-8 is a valid CAS Registry Number.

Physical, spectral and chromatographic properties of all 209 individual PCB congeners
Bolgar,et al.
, p. 2687 - 2705 (2007/10/03)
Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations. -from Authors
