Check Digit Verification of cas no

The CAS Registry Mumber 1552271-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,2,2,7 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1552271-89:
(9*1)+(8*5)+(7*5)+(6*2)+(5*2)+(4*7)+(3*1)+(2*8)+(1*9)=162
162 % 10 = 2
So 1552271-89-2 is a valid CAS Registry Number.

Development of ProPhenol ligands for the diastereo- and enantioselective synthesis of β-hydroxy-α-amino esters

Trost, Barry M.,Miege, Frederic

, p. 3016 - 3019 (2014/03/21)

A zinc-ProPhenol-catalyzed direct asymmetric aldol reaction between glycine Schiff bases and aldehydes is reported. The design and synthesis of new ProPhenol ligands bearing 2,5-trans-disubstituted pyrrolidines was essential for the success of this process. The transformation operates at room temperature and affords syn β-hydroxy-α-amino esters in high yields with good to excellent levels of diastereo- and enantioselectivity.
