Undeca-2t,4t-diene-6,8,10-triynal is a complex organic compound characterized by its unique structure, which consists of an 11-carbon chain with two triple bonds (acetylenic groups) at positions 6, 8, and 10. The compound also features two trans double bonds (alkene groups) at positions 2 and 4. This arrangement of functional groups gives the molecule distinct chemical properties and reactivity. It is an example of an alkyne, which is a hydrocarbon with carbon-carbon triple bonds, and an alkene, which has carbon-carbon double bonds. The compound's name reflects its structure, with "undeca" indicating the presence of 11 carbon atoms, "2t,4t-diene" specifying the trans double bonds at the 2nd and 4th positions, and "6,8,10-triynal" denoting the triple bonds at the 6th, 8th, and 10th positions. This molecule is of interest in organic chemistry due to its potential applications in the synthesis of various compounds and its unique electronic properties.
The CAS Registry Mumber 91635-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,3 and 5 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 91635-03: (7*9)+(6*1)+(5*6)+(4*3)+(3*5)+(2*0)+(1*3)=129 129 % 10 = 9 So 91635-03-9 is a valid CAS Registry Number.
