138812-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138812-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,1 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138812-85:
(8*1)+(7*3)+(6*8)+(5*8)+(4*1)+(3*2)+(2*8)+(1*5)=148
148 % 10 = 8
So 138812-85-8 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).
