Check Digit Verification of cas no

The CAS Registry Mumber 134198-11-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,9 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134198-11:
(8*1)+(7*3)+(6*4)+(5*1)+(4*9)+(3*8)+(2*1)+(1*1)=121
121 % 10 = 1
So 134198-11-1 is a valid CAS Registry Number.

Hypersensitive mechanistic probe studies of cytochrome P450-catalyzed hydroxylation reactions. Implications for the cationic pathway

Toy, Patrick H.,Newcomb, Martin,Hollenberg, Paul F.

, p. 7719 - 7729 (2007/10/03)

Details of the mechanism of cytochrome P450-catalyzed hydroxylation reactions were investigated by oxidation of trans-2-phenyl-1- alkylcyclopropanes (alkyl = methyl (1), ethyl (2), 1-propyl (3), 1- methylethyl (4)) and trans-2-(4-(trifluoromethyl)phenyl)-1-alkylcyclopropanes (alkyl = methyl (5), ethyl (6)). The syntheses of 3 and 6 and their possible oxidation products are reported. Oxidation of the probes with the cytochrome P450 isozyme CYP2B1 gave unrearranged cyclopropylcarbinols as major products and small amounts of ring-opened alcohol products in all cases except for 4. Phenolic products also were produced from substrates 1-4. The maximum lifetimes of putative radical intermediates were less than 1 ps, and the results with substrate 4 require that no intermediate was formed. The results were analyzed in the context of recent mechanistic proposals for cytochrome P450-catalyzed hydroxylations. Oxidation of a 'radical' component in the transition state of an insertion reaction to produce a cation is inconsistent with the results. The results also provide little support for a new alternative mechanism for hydroxylation, the agostic complex model (Collman, J.P.; Chien, A. S.; Eberspacher, T. A.; Brauman, J. I. J. Am. Chem. Soc. 1998, 120, 425). Formation of 'cationic' rearrangement products via solvolysis of first-formed protonated alcohol products produced by insertion of the 'OH+' moiety from iron-complexed hydrogen peroxide also is not supported by the results. The most consistent mechanistic description is the recently reported multistate reactivity paradigm (Shaik, S.; Filatov, M.; Schroder, D.; Schwarz, H. Chem. Eur. J. 1998, 4, 193).
