4683-51-6

4,4-Dimethyl-1,3-cyclopentanedione, also known as diacetyl, is a chemical compound with the molecular formula C7H10O2. It is a colorless, crystalline solid that is soluble in water and has a pungent, buttery odor. This organic compound is widely used in the food industry as a flavoring agent, particularly in the production of butter and butter-flavored products, due to its ability to mimic the taste of butter. It is also used in the synthesis of various chemicals, such as pharmaceuticals and polymers. Diacetyl is produced through the oxidation of 2,3-dimethyl-2-butanol or by the condensation of acetone with acetic acid. It is important to note that while diacetyl is generally recognized as safe (GRAS) by the FDA for use in food, it has been associated with respiratory issues in workers exposed to high levels in industrial settings, highlighting the need for proper safety measures in its production and handling.

4683-51-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4683-51-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,8 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4683-51:
(6*4)+(5*6)+(4*8)+(3*3)+(2*5)+(1*1)=106
106 % 10 = 6
So 4683-51-6 is a valid CAS Registry Number.
