Check Digit Verification of cas no

The CAS Registry Mumber 80630-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,3 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80630-66:
(7*8)+(6*0)+(5*6)+(4*3)+(3*0)+(2*6)+(1*6)=116
116 % 10 = 6
So 80630-66-6 is a valid CAS Registry Number.

Asymmetric Induction during the Aminolysis of 5(4H)-Oxazolones from N-Benzoyl Amino Acids; Almost Specific Formation of One Epimer in the Reaction of the Oxazolone from N-Benzoyl-DL-t-leucine with Methyl L-Prolinate

, p. 4161 - 4163 (2007/10/02)

Asymmetric induction during the aminolysis of 5(4H)-oxazolones from N-benzoyl amino acids was investigated using a series of amino acid esters as amine nucleophiles.The reaction of the oxazolone from N-benzoyl-DL-t-leucine with methyl L-prolinate was found to produce the diastereomeric D-L isomer, almost specifically, under appropriate conditions.
