Check Digit Verification of cas no

The CAS Registry Mumber 157372-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,3,7 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157372-85:
(8*1)+(7*5)+(6*7)+(5*3)+(4*7)+(3*2)+(2*8)+(1*5)=155
155 % 10 = 5
So 157372-85-5 is a valid CAS Registry Number.

Stereoselective synthesis of dienylamines: From amino acids to E-alkene dipeptide isosters

Reginato, Gianna,Gaggini, Francesca,Mordini, Alessandro,Valacchi, Michela

, p. 6791 - 6800 (2007/10/03)

A stereoselective approach to dienylamines is described, starting from enantiomerically enriched stannylated allylamines, which are in turn derived from amino acids. Conveniently the procedure allows to introduce diversity at 1-,2- and 4- positions of the final compounds. Conversion to vinylstannane has been extended to dipeptido aldehydes. The possible elaboration of 4-methyl substituted dienylamines to Boc-Gly-Ψ[(E)-CHCH]-(l,d)-Ala and Boc-Phe -Ψ[(E)-CHCH]-(l,d)-Ala dipeptide isosters is also shown.
