17-Octadecenyl bromide, also known as 1-bromo-17-octadecene, is an organic chemical compound with the molecular formula C18H35Br. It is a brominated derivative of octadecene, a long-chain unsaturated alkene. 17-Octadecenyl bromide is commonly used as a reagent in organic synthesis, particularly in the preparation of various functionalized compounds and polymers. It is also used in the production of surfactants, lubricants, and other specialty chemicals. As a brominated compound, 17-octadecenyl bromide should be handled with care and proper safety precautions due to its potential hazards and reactivity.
Check Digit Verification of cas no
The CAS Registry Mumber 172656-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,6,5 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 172656-11:
(8*1)+(7*7)+(6*2)+(5*6)+(4*5)+(3*6)+(2*1)+(1*1)=140
140 % 10 = 0
So 172656-11-0 is a valid CAS Registry Number.

Synthesis of 13C-labelled ω-hydroxy carboxylic acids of the general formula HO213C-(CH2)n-CH2OH or HO2C-(CH2)n-13CH2OH (n = 12, 16, 20, 28)

13C-labelled ω-hydroxy-carboxylic acids HO213C-(CH2)n-CH2OH or HO2C-(CH2)n-13CH2OH (n = 12, 16, 20, 28) with 13C labels selectively introduced either at the carboxy group or at the primary alcohol function at the end of the hydrocarbon chain have been synthesized. Different synthetic strategies had to be applied depending on the position of the label, the chain length of the respective synthetic target and due to economic considerations. 13C labels in general were introduced by nucleophilic substitution of a suitable leaving group with labelled potassium cyanide and subsequent hydrolysis of the nitriles to produce the corresponding labelled carboxy functions, which may also be reduced to give the labelled primary alcohol group. All new compounds are characterized by GC/MS, IR and NMR methods as well as by elemental analysis.
