153152-98-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153152-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,1,5 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 153152-98:
(8*1)+(7*5)+(6*3)+(5*1)+(4*5)+(3*2)+(2*9)+(1*8)=118
118 % 10 = 8
So 153152-98-8 is a valid CAS Registry Number.

A new synthetic route for the γ-lactone precursors of hydroxyethylene dipeptide isosteres
Sakurai,Hata,Yabe
, 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).
