Check Digit Verification of cas no

The CAS Registry Mumber 64017-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,0,1 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64017-86:
(7*6)+(6*4)+(5*0)+(4*1)+(3*7)+(2*8)+(1*6)=113
113 % 10 = 3
So 64017-86-3 is a valid CAS Registry Number.

Investigations into the mechanism of lactamization of lactones yielding in a novel route to biologically active tryptamine derivatives

Decker, Michael,Nguyen, Thi Thanh Huyen,Lehmann, Jochen

, p. 4567 - 4578 (2007/10/03)

The mechanism of lactamization of corresponding lactones was investigated by means of gas chromatography and synthesis of possible intermediates as references. Lactones react with amines via the amino acid with subsequent elimination of water to the corresponding lactams. In the first step, also hydroxyamides are in equilibrium with the lactones and amines, respectively, which are not able to form the amide though. This mechanism opens a new approach for the synthesis of Nβ-disubstituted tryptamines.
