Check Digit Verification of cas no

The CAS Registry Mumber 60399-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,3,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 60399-05:
(7*6)+(6*0)+(5*3)+(4*9)+(3*9)+(2*0)+(1*5)=125
125 % 10 = 5
So 60399-05-5 is a valid CAS Registry Number.

Ready N-alkylation of enantiopure aminophenols: Synthesis of tertiary aminophenols

Cimarelli, Cristina,Palmieri, Gianni,Volpini, Emanuela

, p. 6089 - 6096 (2007/10/03)

A regioselective indirect alkylation of aminophenols to enantiopure tertiary aminophenols, which are useful chiral ligands for metal-catalysed asymmetric reactions, is reported. This very simple synthetic methodology, through reduction or alkylation of an intermediate benzoxazine, was performed in mild conditions, suitable for the conservation of the configuration of the stereogenic centres. Some crystalline aminophenols show the phenomenon of 'crystallization-induced asymmetric transformation'.
