Octadecanoic acid, 2,2-dimethyl-, also known as 2,2-dimethyloctadecanoic acid or pelargonic acid, is a saturated, branched-chain fatty acid with the chemical formula C20H40O2. It consists of an 18-carbon alkyl chain with two methyl groups attached to the second carbon atom and a carboxylic acid group at the end. Octadecanoic acid, 2,2-dimethyl- is a white crystalline solid with a melting point of 54-56°C and is insoluble in water but soluble in organic solvents. It is commonly used in the production of lubricants, plasticizers, and as an intermediate in the synthesis of various chemicals. Additionally, it has applications in the pharmaceutical and cosmetic industries due to its emollient properties.

Check Digit Verification of cas no

The CAS Registry Mumber 4691-93-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,9 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4691-93:
(6*4)+(5*6)+(4*9)+(3*1)+(2*9)+(1*3)=114
114 % 10 = 4
So 4691-93-4 is a valid CAS Registry Number.
