Check Digit Verification of cas no
The CAS Registry Mumber 19493-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,9 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19493-30:
(7*1)+(6*9)+(5*4)+(4*9)+(3*3)+(2*3)+(1*0)=132
132 % 10 = 2
So 19493-30-2 is a valid CAS Registry Number.

Conformational energies of perfluoroalkanes. 5. Dipole moments of H(CF2)nH and H(CF2)nI
Matsuo, Keizo,Stockmayer, Walter H.
, p. 3307 - 3311 (2007/10/02)
Dielectric and refractive index increments at 25°C are reported for some α,ω-dihydroperfluoroalkanes and α-hydro-ω-iodoperfluoroalkanes in benzene and CCl4. Similar measurements on perfluorocyclohexane and perfluoro-n-hexane are used to deduce effective atomic polarizations for fluorocarbons in solution. The dipole moments obtained lead to a somewhat smaller characteristic ratio for the perfluoroalkane chain than had earlier been estimated by Bates and Stockmayer.
