18281-04-4 Usage
General Description
N-NONDADECANOIC ACID ETHYL ESTER is a chemical compound composed of a long chain fatty acid (n-nonadecanoic acid) esterified with ethyl alcohol. It is commonly used as a flavoring agent in food products, as well as in the production of perfumes and other fragrance products. It is also known for its potential use in biodiesel production. The compound is a colorless liquid with a mild odor, and it is considered safe for use in food and cosmetic products when used in accordance with regulations and guidelines. It can be synthesized through esterification of n-nonadecanoic acid with ethyl alcohol under specific reaction conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 18281-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18281-04:
(7*1)+(6*8)+(5*2)+(4*8)+(3*1)+(2*0)+(1*4)=104
104 % 10 = 4
So 18281-04-4 is a valid CAS Registry Number.
