Check Digit Verification of cas no

The CAS Registry Mumber 111793-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,9 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111793-96:
(8*1)+(7*1)+(6*1)+(5*7)+(4*9)+(3*3)+(2*9)+(1*6)=125
125 % 10 = 5
So 111793-96-5 is a valid CAS Registry Number.

Asymmetric Synthesis with Chiral β-Lactams. α-Substituted Aromatic α-Amino Acids and Their Derivatives through Highly Stereoselective Alkylations

Ojima, Iwao,Chen, Hauh-Jyun C.,Nakahashi, Kazuaki

, p. 278 - 281 (2007/10/02)

A novel route to optically pure α-alkylated aromatic α-amino acids and their dipeptide derivatives was developed through the asymmetric alkylation at the C-3 position of a chiral β-lactam 1 followed by the reductive cleavage of the alkylated β-lactams 2.T
