Check Digit Verification of cas no

The CAS Registry Mumber 91133-36-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,3 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91133-36:
(7*9)+(6*1)+(5*1)+(4*3)+(3*3)+(2*3)+(1*6)=107
107 % 10 = 7
So 91133-36-7 is a valid CAS Registry Number.

Generation of alkyl radicals from alkylsilyl peroxides and their applications to C-N or C-O bond formations

Sakurai, Shunya,Kato, Terumasa,Sakamoto, Ryu,Maruoka, Keiji

, p. 172 - 179 (2018/12/11)

This article describes a novel method for the generation of alkyl radicals from alkylsilyl peroxides and their applications to the Cu-catalyzed mono-N-alkylation of amides or arylamines, and to the O-alkylation of carboxylic acids. The use of alkylsilyl peroxides as alkyl radical sources includes the following synthetic advantages: i) various alkylsilyl peroxides can be readily synthesized from the corresponding alcohols and be stored at bench, and ii) a variety of alkyl radicals can be generated efficiently under mild conditions.

Alkylsilyl Peroxides as Alkylating Agents in the Copper-Catalyzed Selective Mono-N-Alkylation of Primary Amides and Arylamines

Sakamoto, Ryu,Sakurai, Shunya,Maruoka, Keiji

supporting information, p. 9030 - 9033 (2017/07/11)

The copper-catalyzed selective mono-N-alkylation of primary amides or arylamines using alkylsilyl peroxides as alkylating agents is reported. The reaction proceeds under mild reaction conditions and exhibits a broad substrate scope with respect to the alkylsilyl peroxides, as well as to the primary amides and arylamines. Mechanistic studies suggest that the present reaction should proceed through a free-radical process that includes alkyl radicals generated from the alkylsilyl peroxides.
