Check Digit Verification of cas no
The CAS Registry Mumber 74472-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,7 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74472-52:
(7*7)+(6*4)+(5*4)+(4*7)+(3*2)+(2*5)+(1*2)=139
139 % 10 = 9
So 74472-52-9 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
