Check Digit Verification of cas no
The CAS Registry Mumber 19525-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,2 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19525-95:
(7*1)+(6*9)+(5*5)+(4*2)+(3*5)+(2*9)+(1*5)=132
132 % 10 = 2
So 19525-95-2 is a valid CAS Registry Number.

Efficient parallel resolution of pentafluorophenyl active esters using quasi-enantiomeric combinations of oxazolidin-2-ones
Shaye, Najla Al,Chavda, Sameer,Coulbeck, Elliot,Eames, Jason,Yohannes, Yonas
experimental part, p. 439 - 463 (2011/06/17)
The parallel resolution of racemic pentafluorophenyl 2-aryl/ phenylpropanoates and butanoates using an equimolar combination of quasi-enantiomeric Evans oxazolidin-2-ones is discussed. The levels of diastereoselectivity were excellent (>90% de) leading to separable quasi-enantiomeric oxazolidin-2-ones in good yield. This methodology was used to resolve a series of structurally related 2-aryl/phenylpropanoic and butanoic acids.
