18922-88-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18922-88-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18922-88:
138 % 10 = 8
So 18922-88-8 is a valid CAS Registry Number.

Resonance Raman spectra of cytochrome b5 and its mesoheme and deuteroheme (cas 18922-88-8) modifications07/18/2019

Resonance Raman spectra of proto-, meso-, and deuterohemes isolated in cytochrome b5 have been recorded and effects due to sidegroup substituents noted. A one-to-one correspondence can be made between the fundamental Raman bands of mesoheme and deuteroheme, enabling identification of inductive e...detailed

Reactions of Iron Porphyrins with Methyl Radicals

Brault, D.,Neta, P.

, p. 2705 - 2710 (1981)

The reactions of methyl radicals with ferric, ferrous, and iron-free deuteroporphyrin have been investigated in neutral and alkaline water-2-propanol mixtures.Steady-state radiolysis of methyl chloride saturated solutions of ferric deuteroporphyrin, or ch

One-Electron Reduction of Ferrideuteroporphyrin IX and Reaction of the Oxidized and Reduced Forms with Chlorinated Methyl Radicals

Brault, D.,Bizet, C.,Morliere, P.,Rougee, M.,Land, E. J.,et al.

, p. 1015 - 1020 (1980)

α-Hydroxyisopropyl radicals prepared by fast electron irradiation of aqueous solutions containing 2-propanol and acetone were found to reduce monomeric ferrideuteroporphyrin to ferrodeuteroporphyrin with a rate constant of 3.7*108 M-1 s-1.Relaxation of the coordination sphere is found to proceed with a rate constant k > 5*105 s-1.Irradiation of such solution in the added presence of various concentrations of CCl4, CHCl3, or CH2Cl2 enable studies to be made of the reactions of ferri- and ferrodeuteroporphyrin with chlorinated methyl radicals.No reaction of ferrideuterroporphyrin with CCl3 could be detected (k 6 M-1 s-1).For ferrrodeuteroporphyrin it appears that a rapid reaction (k = (2 +/- 1)*109 M-1 s-1) gives a complex (DPFeII-CH3-nCln) which undergoes further reaction as shown by transient spectral modifications.These results suggest that ferrous cytochrome P450 is likely to react rapidly with chlorinated radicals.A model for the toxicity and detoxification of CCl4 is proposed.
