858493-07-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 858493-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,4,9 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 858493-07:
(8*8)+(7*5)+(6*8)+(5*4)+(4*9)+(3*3)+(2*0)+(1*7)=219
219 % 10 = 9
So 858493-07-9 is a valid CAS Registry Number.

Benzylation of nitroalkanes using copper-catalyzed thermal redox catalysis: Toward the facile C-alkylation of nitroalkanes

Gildner, Peter G.,Gietter, Amber A. S.,Cui, Di,Watson, Donald A.

supporting information; experimental part, p. 9942 - 9945 (2012/08/07)

The C-alkylation of nitroalkanes under mild conditions has been a significant challenge in organic synthesis for more than a century. Herein we report a simple Cu(I) catalyst, generated in situ, that is highly effective for C-benzylation of nitroalkanes using abundant benzyl bromides and related heteroaromatic compounds. This process, which we believe proceeds via a thermal redox mechanism, allows access to a variety of complex nitroalkanes under mild reaction conditions and represents the first step toward the development of a general catalytic system for the alkylation of nitroalkanes.
