General Description
2,4-Pentanedione, 3-(1-hydroxyethylidene)- is a chemical compound with the molecular formula C7H12O3. It is a diketone with a hydroxyethylidene group attached to the third carbon atom. 2,4-Pentanedione, 3-(1-hydroxyethylidene)- is commonly used as a flavoring agent in food and beverages due to its buttery and creamy flavor profile. It is also used in the production of fragrances and as a chemical intermediate in the synthesis of other organic compounds. However,
Check Digit Verification of cas no
The CAS Registry Mumber 1704-16-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1704-16:
(6*1)+(5*7)+(4*0)+(3*4)+(2*1)+(1*6)=61
61 % 10 = 1
So 1704-16-1 is a valid CAS Registry Number.

Unusual aluminum chloride-assisted conversion of isopropenyl acetate into 3-acetyl- and 3,5-diacetyl-2,6-dimethyl-4H-pyran-4-ones
Novikov,Shestak,Denisenko
experimental part, p. 1600 - 1604 (2011/05/04)
Reflux of isopropenyl acetate with an excess of AlCl3 in 1,2-dichloroethane affords 3,5-diacetyl-2,6-dimethyl-4H-pyran-4-one in 17% yield. The mild acidic cleavage of the latter (2% HCl, 20°C, 16 h) gives 3-acetyl-2,6-dimethyl-4H-pyran-4-one in 87% yield, whereas this reaction under more drastic conditions (17% HCl, reflux, 3 h) gives 2,6-dimethyl-4H-pyran-4-one in 61% yield.
