47091-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 47091-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,0,9 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 47091-20:
(7*4)+(6*7)+(5*0)+(4*9)+(3*1)+(2*2)+(1*0)=113
113 % 10 = 3
So 47091-20-3 is a valid CAS Registry Number.

Selective C-N bond oxidation: demethylation of N-methyl group in N-arylmethyl-N-methyl-α-amino esters utilizing N-iodosuccinimide (NIS)

Katoh, Takahiro,Watanabe, Tsunefumi,Nishitani, Mitsuyoshi,Ozeki, Minoru,Kajimoto, Tetsuya,Node, Manabu

, p. 598 - 600 (2008/09/16)

Demethylation of N-methyl group in N-methyl-N-arylmethyl-α-amino esters was accomplished by the oxidation of the amino group using the N-iodosuccinimide (NIS)/acetonitrile system followed by treatment with O-methylhydroxylamine hydrochloride. This combina

Total synthesis of the cyclic depsipeptide leualacin

McLaren

, p. 6082 - 6084 (2007/10/03)

The fungal metabolite leualacin (1), a potent calcium channel antagonist, was synthesized in 15 steps from commercially available amino acids in 25% overall yield using standard solution methods. The synthesis is general and thus would accommodate the incorporation of amino acid replacements as well as the inclusion of peptide mimics and isosteres.
