1333261-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1333261-91-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,6 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1333261-91:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*6)+(3*1)+(2*9)+(1*1)=128
128 % 10 = 8
So 1333261-91-8 is a valid CAS Registry Number.

Concise pathway to new multifunctionalized constrained pentacin derivatives by means of two stereospecific tandem reactions

Coursindel, Thibault,Martinez, Jean,Parrot, Isabelle

, p. 4519 - 4522 (2011)

Starting from Boc-activated diketopiperazines, original bicyclic derivatives of trans-and cis-2-aminocyclopentane carboxylic acid were prepared by using two stereospecific tandem reactions. One of them is a tandem transannular rearrangement of activated lactams/alkylation process leading to the stereoselective synthesis of suitably chiral pyrrolidine-2, 4-diones, allowing subsequent Michael-initiated ring closure, a simple and concise route to original multifunctionalized alicyclic ss-amino esters.
