Propionic acid 3-methyl-but-2-enyl ester, also known as 3-methylbut-2-enyl propionate, is an organic compound with the chemical formula C7H12O2. It is an ester derived from propionic acid and 3-methylbut-2-en-1-ol, featuring a propionate group (CH3CH2COO-) and a 3-methylbut-2-enyl group (CH2=C(CH3)CH2-). This colorless liquid is characterized by a fruity, apple-like odor and is commonly used in the flavor and fragrance industry to impart a green, fruity, and apple-like note to various products. It is also found in natural sources such as apples, pears, and other fruits, contributing to their characteristic aroma. The compound is synthesized through the esterification of propionic acid with 3-methylbut-2-en-1-ol, and its use in food, beverages, and cosmetics is regulated to ensure safety and quality.

Check Digit Verification of cas no

The CAS Registry Mumber 1189-60-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1189-60:
(6*1)+(5*1)+(4*8)+(3*9)+(2*6)+(1*0)=82
82 % 10 = 2
So 1189-60-2 is a valid CAS Registry Number.
