Check Digit Verification of cas no
The CAS Registry Mumber 38380-07-3 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 38380-07:
(7*3)+(6*8)+(5*3)+(4*8)+(3*0)+(2*0)+(1*7)=123
123 % 10 = 3
So 38380-07-3 is a valid CAS Registry Number.

Mechanism of PCBs formation from the pyrolysis of chlorobenzenes
Liu, Peng-Yan,Zheng, Ming-Hui,Zhang, Bing,Xu, Xiao-Bai
, p. 783 - 785 (2007/10/03)
Polychlorinated biphenyls (PCBs) were formed by pyrolysis of chlorobenzenes in a HCl atmosphere. Varieties of substituted chlorobenzenes were used as model compounds to optimize the condensation reaction. Lower chlorinated benzenes produce more PCBs than that of higher ones. Up to 0.7 μg PCBs/mg 1,2,3-trichlorobenzene was produced through the condensation reaction.
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
