149818-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149818-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,8,1 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 149818-80:
(8*1)+(7*4)+(6*9)+(5*8)+(4*1)+(3*8)+(2*8)+(1*0)=174
174 % 10 = 4
So 149818-80-4 is a valid CAS Registry Number.

A new synthetic route for the γ-lactone precursors of hydroxyethylene dipeptide isosteres

, p. 5939 - 5942 (2007/10/02)
δ-Phthalimido-γ-ketoesters were obtained by the Pd catalyzed coupling reaction between acid chlorides and organozinc reagents derived from β-iodoesters, and were converted into the γ-lactones precursors of Phe-ψ[H.E.]-Ala and Phe-ψ[H.E.]-Pro (15a,b-18a,b).
