2-Butenoic acid, 3-hydroxy-, methyl ester, (E)- (9CI) is a chemical compound with the molecular formula C5H8O3. It is an organic ester derived from 2-butenoic acid and characterized by the presence of a double bond (E) between the second and third carbon atoms. 2-Butenoic acid, 3-hydroxy-, methyl ester, (E)- (9CI) is also known as methyl 3-hydroxy-2-butenoate or methyl sorbate. It is a colorless liquid with a fruity, apple-like odor and is used as a flavoring agent in the food and beverage industry. The compound is synthesized by esterification of 3-hydroxy-2-butenoic acid with methanol, and it is soluble in most organic solvents. Due to its reactive nature, it is sensitive to light, heat, and oxygen, which can lead to degradation and loss of its characteristic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 4525-24-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,2 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4525-24:
(6*4)+(5*5)+(4*2)+(3*5)+(2*2)+(1*4)=80
80 % 10 = 0
So 4525-24-0 is a valid CAS Registry Number.
