Check Digit Verification of cas no

The CAS Registry Mumber 484051-36-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,4,0,5 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 484051-36:
(8*4)+(7*8)+(6*4)+(5*0)+(4*5)+(3*1)+(2*3)+(1*6)=147
147 % 10 = 7
So 484051-36-7 is a valid CAS Registry Number.

An access to (Z)-ethylenic pseudodipeptides based on ring-closing metathesis

Boucard, Valérie,Sauriat-Dorizon, Hélène,Guibé, Fran?ois

, p. 7275 - 7290 (2007/10/03)

A new access to enantiopure (Z)-ethylenic pseudopeptides, starting from the chiral pool of amino acids and enantiopure 2-substituted-but-3-enoic acids is proposed and illustrated by the syntheses of the (Z)-ethylenic pseudopeptidic analogs of L-Phe-L-Phe, L-Phe-D-Phe, L-Phe-L-Val, L-Phe-D-Val and racemic (LL,DD) and (LD,DL) (phenyl)Gly-Phe. The key-steps of these syntheses are a ring-closing metathesis, catalysed by Grubbs' ruthenium alkykidene complexes, on diethylenic amides and the hydrolytic cleavage of the resulting dihydropyridones under mild conditions through intermediate formation of cyclic imidates.
