Check Digit Verification of cas no

The CAS Registry Mumber 197784-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,8 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 197784-44:
(8*1)+(7*9)+(6*7)+(5*7)+(4*8)+(3*4)+(2*4)+(1*4)=204
204 % 10 = 4
So 197784-44-4 is a valid CAS Registry Number.

Asymmetric synthesis of a conformationally constrained N-phosphonoalkyl dipeptide

Wang, Qian,Pfeiffer, Bruno,Tucker, Gordon C.,Royer, Jacques,Husson, Henri-Philippe

, p. 2477 - 2480 (1997)

An asymmetric synthesis has been developed to prepare a phosphono-protected (2S, 6R)-6-phosphono-piperidine-2-carboxylic acid and its (2R, 6S) isomer. Coupling with tryptophan derivative afforded conformationally constrained N-phosphonoalkyl dipeptides (S,S,R)-2 and (S,R,S)-14 which have been both evaluated as human matrix metalloprotease inhibitors.
