93620-38-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93620-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,2 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93620-38:
(7*9)+(6*3)+(5*6)+(4*2)+(3*0)+(2*3)+(1*8)=133
133 % 10 = 3
So 93620-38-3 is a valid CAS Registry Number.

Mechanochemical enzymatic resolution of N-benzylated-β3-amino esters

Pérez-Venegas, Mario,Reyes-Rangel, Gloria,Neri, Adrián,Escalante, Jaime,Juaristi, Eusebio

, p. 1728 - 1734 (2017/09/27)

The use of mechanochemistry to carry out enantioselective reactions has been explored in the last ten years with excellent results. Several chiral organocatalysts and even enzymes have proved to be resistant to milling conditions, which allows for rather efficient enantioselective transformations under ball-milling conditions. The present article reports the first example of a liquid-assisted grinding (LAG) mechanochemical enzymatic resolution of racemic β3-amino esters employing Candida antarctica lipase B (CALB) to afford highly valuable enantioenriched N-benzylated-β3-amino acids in good yields. Furthermore the present protocol is readily scalable.
