89724-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89724-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,2 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89724-87:
(7*8)+(6*9)+(5*7)+(4*2)+(3*4)+(2*8)+(1*7)=188
188 % 10 = 8
So 89724-87-8 is a valid CAS Registry Number.

Some Observations Concerning the Lactonization of 3-Aroylpropionic Acids
Tsolomitis, A.,Sandris, C.
, p. 1545 - 1548 (2007/10/02)
The ease of lactonization og the γ-keto acids ArCOCH2CH2COOH is shown to depend on the nature of the aryl group: the presence of electron-releasing substituents on the aryl group results in a more rapid reaction as compared to the presence of electron-wit
