67159-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67159-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,5 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67159-52:
(7*6)+(6*7)+(5*1)+(4*5)+(3*9)+(2*5)+(1*2)=148
148 % 10 = 8
So 67159-52-8 is a valid CAS Registry Number.

Resolution of 4-phenyl-2-pyrrolidinone: A versatile synthetic intermediate
Zelle
, p. 1023 - 1026 (2007/10/02)
A resolution of 4-phenyl-2-pyrrolidinone is described. The resulting enantiomerically pure pyrrolidinones are exploited as precursor to 3-phenylpyrrolidines and 3-phenyl-γ-amino acids (4-amino-3-phenylbutanoic acid derivatives).
