Check Digit Verification of cas no

The CAS Registry Mumber 634878-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,8,7 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 634878-89:
(8*6)+(7*3)+(6*4)+(5*8)+(4*7)+(3*8)+(2*8)+(1*9)=210
210 % 10 = 0
So 634878-89-0 is a valid CAS Registry Number.

Synthesis of (±)-Lasubine II Using N-Methoxyamines

Yokoyama, Takashi,Fukami, Yutaro,Sato, Takaaki,Chida, Noritaka

, p. 470 - 473 (2016/03/08)

The synthesis of (±)-lasubine II has been achieved through a three-component allylation capitalizing on the unique properties of N-methoxyamines. This reaction enabled the installation of all the carbon atoms of lasubineII in a single operation. The N-met

A New and Practical Procedure for the Bruylants Reaction. Zinc-Mediated Synthesis of Tertiary Homoallylamines and β-Aminoesters

Bernardi, Luca,Bonini, Bianca F.,Capitò, Elena,Dessole, Gabriella,Fochi, Mariafrancesca,Comes-Franchini, Mauro,Ricci, Alfredo

, p. 1778 - 1782 (2007/10/03)

N,N-Disubstituted α-aminonitriles undergo Bruylants reaction under Barbier and Reformatsky conditions with activated halides, in the presence of zinc and 10 mol% HOAc. The high yields and the simple operational conditions make this reaction an appealing, approach to N,N-disubstituted homoallylamines and β-aminoesters.
