104293-47-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104293-47-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,9 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104293-47:
(8*1)+(7*0)+(6*4)+(5*2)+(4*9)+(3*3)+(2*4)+(1*7)=102
102 % 10 = 2
So 104293-47-2 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).
