221293-02-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221293-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,9 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221293-02:
(8*2)+(7*2)+(6*1)+(5*2)+(4*9)+(3*3)+(2*0)+(1*2)=93
93 % 10 = 3
So 221293-02-3 is a valid CAS Registry Number.

Synthesis of the Entomopathogenic Fungus Metabolites Militarinone C and Fumosorinone A

Bruckner, Sebastian,Weise, Marie,Schobert, Rainer

, p. 10805 - 10812 (2018/08/03)

Militarinone C and fumosorinone A, 3-oligoenoyltetramic acids produced by insect pathogenic fungi, were synthesized for the first time. The pyrrolidine-2,4-dione ring was closed through a late-stage Dieckmann condensation of N-(β-ketoacyl) derivatives of tyrosine, obtained by its acylation with either thioesters or Meldrum's acid derivatives bearing the all-trans-polyene side chain. The latter was built up from (S)-citronellol via an Evans methylation and Wittig or HWE olefinations.

Stereoisomeric indole compounds, process for the preparation of the same, and use thereof

-

Page column 16, (2010/11/30)

Novel stereoisomeric indole compounds of the formula (1), a process for the preparation the same, and use thereof wherein, Y represents the group wherein, X represents alkyl group having 1-5 carbon atom(s) (the alkyl group may be substituted with hydroxyl group, carboxyl group, amino group, methylthio group, mercapto group, guanidyl group, imidazolyl group or benzyl group), and R1and R2represent each independently hydrogen atom, alkyl group, aralkyl group, cycloalkyl group or aryl group;R represents hydrogen atom, alkyl group, aralkyl group, cycloalkyl group, aryl group, monovalent metal, amine or ammonium; and the symbol ‘*’ represents a position of an asymmetric carbon atom. The above-mentioned compounds can be prepared by condensing tryptophan with a stereoisomeric α-amino acid or carboxylic acid to form an amide form and subjecting or carboxylic acid to form an amide form and subjecting the amide form to oxidative cyclization to form an oxazole ring at once. The compounds exhibit; physiological activities such as inhibitory action against lipid peroxidation, and can be therefore utilized in the form of lipid peroxidation inhibitors containing the same as the active ingredient.

First total synthesis of martefragin A, a potent inhibitor of lipid peroxidation isolated from sea alga

Nishida, Atsushi,Fuwa, Mihoko,Fujikawa, Yukiko,Nakahata, Etsuko,Furuno, Asako,Nakagawa, Masako

, p. 5983 - 5986 (2007/10/03)

The first total synthesis of martefragin A, a potent inhibitor of lipid peroxidation isolated from sea alga, has been accomplished and the absolute configurations of two stereogenic centers were determined. Synthetic martefragin A, its stereo isomers, and some analogs showed strong inhibitory activity against lipid peroxidation rat liver microsome.
