Check Digit Verification of cas no
The CAS Registry Mumber 12036-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12036-04:
(7*1)+(6*2)+(5*0)+(4*3)+(3*6)+(2*0)+(1*4)=53
53 % 10 = 3
So 12036-04-3 is a valid CAS Registry Number.

Kinetic study of the recombination reaction of gas phase Pd(a1S0) with O2 from 294 to 523 K
Campbell, Mark L.,Plane, John M. C.
, p. 3747 - 3751 (2003)
The gas-phase removal rate constants for the reaction of ground-state palladium (a1S0) with oxygen in argon buffer are reported as a function of temperature and pressure. Palladium atoms were produced by the photodissociation of palladium(II) trifluoroacetate and detected by laser-induced fluorescence. The reaction is pressure dependent, indicating recombination to form PdO2. Falloff behavior is observed at pressures above about 20 Torr. Quantum calculations indicate that the reaction proceeds on a triplet surface to form bent PdO2(3A″), which has a low frequency bending mode of only 129 cm-1 and a bond energy D0 = 95 kJ mol-1. RRKM theory, fitted to the experimental data, shows that D0 should lie below 155 kJ mol-1 and predicts the following expression for the rate coefficient from 200 to 600 K: krec,0 = 1.09 × 10-30 (T/300 K)-2.76 cm6 molecule-2 s-1, krec,∞ = 2.52 × 10-10 exp(-69.3/T) cm3 molecule-1 s-1, and Fc = 0.61.
