Check Digit Verification of cas no
The CAS Registry Mumber 154089-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,0,8 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 154089-44:
(8*1)+(7*5)+(6*4)+(5*0)+(4*8)+(3*9)+(2*4)+(1*4)=138
138 % 10 = 8
So 154089-44-8 is a valid CAS Registry Number.

A new evidence of the high-valent oxo-metal radical cation intermediate and hydrogen radical abstract mechanism in hydrocarbon hydroxylation catalyzed by metalloporphyrins

Forty metalloporphyrins with different peripheral substituents (R) on the porphyrin ring, RTPPM(III)Cl and [RTPPM(III)]2O (M= Fe, Mn), were synthesized, and were used to catalyze cyclohexane hydroxylation with iodosobenzene under mild conditions. A Hammett relationship, log k = ρσ + c, was shown to exist between the rate constants k of the cyclohexane hydroxylation and Hammett constants σ of substituents on the porphyrin rings. The value of the reaction constant ρ changed from 0.3 to 0.5 for the cyclohexane oxidation catalyzed by metalloporphyrins, and electron- withdrawing groups increased the reaction speeds. This means that the reaction mediator was a radical cation, and that the rate-determining step of the reaction was a radical reaction. These research results provided a new evidence for the high-valent oxo-metal radical cation intermediate and hydrogen radical abstraction mechanism in hydrocarbon hydroxylation catalyzed by metalloporphyrins.
