64502-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64502-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64502-98:
(7*6)+(6*4)+(5*5)+(4*0)+(3*2)+(2*9)+(1*8)=123
123 % 10 = 3
So 64502-98-3 is a valid CAS Registry Number.

A Mononuclear Non-heme Manganese(III)-Aqua Complex as a New Active Oxidant in Hydrogen Atom Transfer Reactions

Sankaralingam, Muniyandi,Lee, Yong-Min,Karmalkar, Deepika G.,Nam, Wonwoo,Fukuzumi, Shunichi

supporting information, p. 12695 - 12699 (2018/10/20)

A mononuclear non-heme Mn(III)-aqua complex, [(dpaq)MnIII(OH2)]2+ (1, dpaq = 2-[bis(pyridin-2-ylmethyl)]amino-N-quinolin-8-yl-acetamidate), is capable of conducting hydrogen atom transfer (HAT) reactions much more efficiently than the corresponding Mn(III)-hydroxo complex, [(dpaq)MnIII(OH)]+ (2); the high reactivity of 1 results from the positive one-electron reduction potential of 1 (Ered vs SCE = 1.03 V), compared to that of 2 (Ered vs SCE = -0.1 V). The HAT mechanism of 1 varies between electron transfer followed by proton transfer and one-step concerted proton-coupled electron transfer, depending on the one-electron oxidation potentials of substrates. To the best of our knowledge, this is the first example showing that metal(III)-aqua complex can be an effective H-atom abstraction reagent.
