Check Digit Verification of cas no
The CAS Registry Mumber 40920-68-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,2 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40920-68:
(7*4)+(6*0)+(5*9)+(4*2)+(3*0)+(2*6)+(1*8)=101
101 % 10 = 1
So 40920-68-1 is a valid CAS Registry Number.

The reaction of acetylacetone with α,β-enones in the presence of potassium carbonate affords 6-acetylcyclohex-2-enones. The assembly of two acetoacetate and one alkanal molecules gives 3,5-dialkylcyclohex-2-enones. Facile one-pot procedures for these reactions were developed.
Recyclization of 1,4-dihydropyridine derivatives in acidic medium

The recyclization of 1,4-dihydropyridines in aqueous-alcoholic hydrochloric acid medium proceeds with cleavage of a C-N bond and pyridine ring opening. Cyclohexenone derivatives are formed as a result of the subsequent intramolecular crotonic condensation of the acyclic intermediate. The leaving carbonyl substituents depart simultaneously with recyclization, depending on the acidity of the reaction medium.
