General Description
(9E)-undec-9-enenitrile is a chemical compound with the molecular formula C11H19N. It is a nitrile, or a compound containing a cyano group (–C≡N), which is a functional group consisting of a carbon atom triple-bonded to a nitrogen atom. (9E)-undec-9-enenitrile contains a double bond in the nine-carbon chain, with the characteristic "E" configuration indicating that the double bond has the higher-priority substituents on opposite sides of the bond. (9E)-undec-9-enenitrile is used in organic synthesis and as a starting material for the production of other organic compounds. It is also sometimes used in the flavor and fragrance industry, adding a characteristic odor or taste to products.
Check Digit Verification of cas no
The CAS Registry Mumber 131379-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,7 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131379-26:
(8*1)+(7*3)+(6*1)+(5*3)+(4*7)+(3*9)+(2*2)+(1*6)=115
115 % 10 = 5
So 131379-26-5 is a valid CAS Registry Number.

METHOD FOR THE CONTROLLED HYDROFORMYLATION AND ISOMERIZATION OF A NITRILE/ESTER/OMEGA UNSATURATED FATTY ACID
-
Paragraph 0162-0163, (2016/05/24)
A method to synthesize a fatty nitrile/ester aldehyde comprising the following steps: 1) hydroformylation of a ω-unsaturated fatty nitrile/ester/acid substrate under particular conditions of partial pressure, temperature, reaction time, conversion rate of the ω-unsaturated fatty nitrile/ester/acid reactant, catalyst, [substrate]/[metal] molar ratio and [ligand]/[metal] molar ratio so as after the reaction to obtain: a hydroformylation product comprising at least one fatty nitrile/ester/acid aldehyde of formula: OHC—(CH2)r+2—R, andan isomerate comprising at least one fatty nitrile/ester/acid isomer with internal unsaturation in which at least 80% of the internal isomer(s) of the isomerate are formed of the ω-1 unsaturated isomer of formula CH3—CH═CH—(CH2)r?1—R; followed by:2) separation and recovery of the fatty nitrile/ester/acid aldehyde and of the isomerate.
