General Description
"(R)-N,N'-Bis(p-methoxybenzyl)-3-isopropyl-piperazine-2,5-dione" is a chemical compound that belongs to the class of piperazine-diones. It contains two p-methoxybenzyl groups attached through nitrogen atoms and an isopropyl group attached to the third carbon atom of the piperazine ring. (R)-N,N'-Bis(p-methoxybenzyl)-3-isopropyl-piperazine-2,5-dione adopts an 'R' configuration, indicating the direction of rotation of plane-polarized light. Piperazine-diones generally exhibit useful biological activities and the presence of methoxybenzyl and isopropyl groups, and stereochemical specificity, might influence the compound's bioactivity. The exact properties, including the physical, chemical, and bioactive properties, may be determined through further experimental studies.
Check Digit Verification of cas no
The CAS Registry Mumber 205517-34-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,1 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 205517-34:
(8*2)+(7*0)+(6*5)+(5*5)+(4*1)+(3*7)+(2*3)+(1*4)=106
106 % 10 = 6
So 205517-34-6 is a valid CAS Registry Number.

A chiral relay auxiliary for the synthesis of homochiral α-amino acids
Bull, Steven D.,Davies, Stephen G.,Epstein, Simon W.,Leech, Michael A.,Ouzman, Jacqueline V. A.
, p. 2321 - 2330 (2007/10/03)
A new chiral auxiliary (3S)-N,N′-bis(p-methoxybenzyl)-3-isopropylpiperazine-2,5-dione 7 has been developed for the asymmetric synthesis of α-amino acids. The auxiliary 7 employs a novel chiral relay network based on non-stereogenic N-benzyl protecting groups which enhance the diastereoselectivity observed during alkylation of its C6 enolate 25.
