4082-55-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4082-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,8 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4082-55:
(6*4)+(5*0)+(4*8)+(3*2)+(2*5)+(1*5)=77
77 % 10 = 7
So 4082-55-7 is a valid CAS Registry Number.

Two triterpenyl fatty acid esters from fagonia cretica as lipoxygenase inhibitors

Nawaz, Zahid,Ahmed, Ejaz,Sharif, Ahsan,Sajid, Anam,Arshed, Faiza,Arshad, Muhammad,Anjum, Muhammad Imran,Razaq, Abdul

, p. 406 - 409 (2018/06/06)

Two triterpenyl fatty acid esters were isolated from the chloroform soluble fraction of Fagonia cretica and their structures elucidated as 3β-12-ursen-3yl-docosanoate (1) and 3β-12-ursen-3yl-nonacosanoate (2) by 1D-NMR, 2D-NMR, mass spectrometric and chemical analyses. Both new compounds were also evaluated for their lipoxygenase inhibitory potential using Baicalein as a standard.

Synthesis of Very Long Fatty Acid Methyl Esters

Kling, Marcel R.,Easton, Christopher J.,Poulos, Alf

, p. 1183 - 1190 (2007/10/02)

Phosphoranes, produced by treating alkyltriphenylphosphonium bromides with lithium hexamethyldisilazide, reacted with ω-oxo esters to give modest yields of the corresponding methyl cis-alkenoates.By an alternative method, treatment of ω-iodo esters with the complexes formed from reactions of alkylcopper(I) and Grignard reagents gave methyl alkanoates, cis-alkenoates, and methylene-interrupted cis,cis-alka-dienoates and cis,cis,cis-trienoates.The stereochemical integrity of the esters was determined by 13C NMR spectroscopy.
