Check Digit Verification of cas no

The CAS Registry Mumber 70841-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,4 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70841-77:
(7*7)+(6*0)+(5*8)+(4*4)+(3*1)+(2*7)+(1*7)=129
129 % 10 = 9
So 70841-77-9 is a valid CAS Registry Number.

Enantioselective decarboxylation-reprotonation of an α-amino malonate derivative as a route to optically enriched cyclic α-amino acid

Rogers, Louis M.-A.,Rouden, Jacques,Lecomte, Ludovic,Lasne, Marie-Claire

, p. 3047 - 3050 (2003)

Chiral tertiary amines have been examined as enantioselective decarboxylation-reprotonation reagents for the synthesis of α-amino acids via α-aminomalonates. N-Acetyl pipecolic acid ethyl ester, as a model compound, was obtained in good yield and 52% enantiomeric excess using a quinidine derived base.
