Check Digit Verification of cas no

The CAS Registry Mumber 1308658-79-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,8,6,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1308658-79:
(9*1)+(8*3)+(7*0)+(6*8)+(5*6)+(4*5)+(3*8)+(2*7)+(1*9)=178
178 % 10 = 8
So 1308658-79-8 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

, p. 439 - 463 (2011)

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.
