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.

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.
