5345-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5345-40-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5345-40:
(6*5)+(5*3)+(4*4)+(3*5)+(2*4)+(1*0)=84
84 % 10 = 4
So 5345-40-4 is a valid CAS Registry Number.

To reveal the scope of the syntheses of 3-aryl-2-quinolinones from 2-nitro-α-phenylcinnamic acids, the isomerization of (E)-2-amino-α- phenylcinnamic acids was studied. The results showed that (E)-2-amino-α- phenylcinnamic acids were isomerized to its (Z)
