Undecanoic acid pentyl ester, commonly known as undecyl pentanoate, is an organic compound with the chemical formula C15H30O2. It is a colorless liquid with a mild, fruity odor and is derived from the esterification of undecyl alcohol and pentanoic acid. This ester is widely used in the fragrance industry as a fixative and scent enhancer, particularly in fruity and floral compositions. It is also employed as a solvent and a component in various cosmetic and personal care products due to its ability to dissolve other ingredients and improve the texture of formulations. Undecyl pentanoate is considered to be relatively non-toxic and non-irritating, making it a safe option for use in consumer products.

Check Digit Verification of cas no

The CAS Registry Mumber 81186-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,8 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81186-23:
(7*8)+(6*1)+(5*1)+(4*8)+(3*6)+(2*2)+(1*3)=124
124 % 10 = 4
So 81186-23-4 is a valid CAS Registry Number.
