Check Digit Verification of cas no

The CAS Registry Mumber 121445-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121445-52:
(8*1)+(7*2)+(6*1)+(5*4)+(4*4)+(3*5)+(2*5)+(1*2)=91
91 % 10 = 1
So 121445-52-1 is a valid CAS Registry Number.

First one-pot copper-catalyzed synthesis of α-hydroxy-β-amino acids in water. A new protocol for preparation of optically active norstatines

Fringuelli, Francesco,Pizzo, Ferdinando,Rucci, Mauro,Vaccaro, Luigi

, p. 7041 - 7045 (2007/10/03)

α-Hydroxy-β-amino acids were synthesized with excellent yields for the first time in water and by a simple procedure based on a copper catalytic cycle, which included the recovery and reuse of the catalyst and is possible to realize by using only water as reaction medium.
