Phthaloyldioxydi-acetic acid diethyl ester, also known as diethyl phthalate, is an organic compound with the chemical formula C12H14O6. It is a colorless, oily liquid that is soluble in most organic solvents and has a slight, pleasant odor. This ester is formed by the reaction of phthalic anhydride with ethylene glycol and is widely used as a plasticizer in the production of various materials, including cellulose acetate, polyvinyl chloride (PVC), and polystyrene. Diethyl phthalate is also employed as a solvent for resins, lacquers, and inks, as well as a fragrance component in perfumes and cosmetics. However, it is important to note that due to its potential health risks, its use in certain applications, particularly those involving direct contact with food or skin, is regulated or restricted in many countries.
The CAS Registry Mumber 1830-13-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 0 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1830-13: (6*1)+(5*8)+(4*3)+(3*0)+(2*1)+(1*3)=63 63 % 10 = 3 So 1830-13-3 is a valid CAS Registry Number.
