Check Digit Verification of cas no

The CAS Registry Mumber 16165-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16165-40:
(7*1)+(6*6)+(5*1)+(4*6)+(3*5)+(2*4)+(1*0)=95
95 % 10 = 5
So 16165-40-5 is a valid CAS Registry Number.

On the absolute photoionization cross section and dissociative photoionization of cyclopropenylidene

Holzmeier, Fabian,Fischer, Ingo,Kiendl, Benjamin,Krueger, Anke,Bodi, Andras,Hemberger, Patrick

, p. 9240 - 9247 (2016/04/09)

We report the determination of the absolute photoionization cross section of cyclopropenylidene, c-C3H2, and the heat of formation of the C3H radical and ion derived by the dissociative ionization of the carbene. Vacuum ultraviolet (VUV) synchrotron radiation as provided by the Swiss Light Source and imaging photoelectron photoion coincidence (iPEPICO) were employed. Cyclopropenylidene was generated by pyrolysis of a quadricyclane precursor in a 1 : 1 ratio with benzene, which enabled us to derive the carbene's near threshold absolute photoionization cross section from the photoionization yield of the two pyrolysis products and the known cross section of benzene. The cross section at 9.5 eV, for example, was determined to be 4.5 ± 1.4 Mb. Upon dissociative ionization the carbene decomposes by hydrogen atom loss to the linear isomer of C3H+. The appearance energy for this process was determined to be AE0K(c-C3H2; l-C3H+) = 13.67 ± 0.10 eV. The heat of formation of neutral and cationic C3H was derived from this value via a thermochemical cycle as ΔfH0K(C3H) = 725 ± 25 kJ mol-1 and ΔfH0K(C3H+) = 1604 ± 19 kJ mol-1, using a previously reported ionization energy of C3H.
