7145-23-5 Usage
General Description
2,3-DIMETHYL-3-HEXENE is a chemical compound with the molecular formula C8H16. It is an organic compound classified as an alkene, which means it contains a carbon-carbon double bond. This chemical is a clear, colorless liquid with a faint odor, and it is insoluble in water. 2,3-DIMETHYL-3-HEXENE is commonly used as a starting material in the synthesis of various other organic compounds. It is also used in the production of fragrances, flavors, and other specialty chemicals. Additionally, it is used as a solvent in some industrial processes. However, it is important to handle this chemical with caution, as it may be harmful if inhaled, absorbed through the skin, or ingested.
Check Digit Verification of cas no
The CAS Registry Mumber 7145-23-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,4 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7145-23:
(6*7)+(5*1)+(4*4)+(3*5)+(2*2)+(1*3)=85
85 % 10 = 5
So 7145-23-5 is a valid CAS Registry Number.

Scope and Regiochemical Control of the Allylpotassium Reaction in the Synthesis of Sterols with Unsaturated Side Chains
Giner, Jose-Luis,Margot, Christian,Djerassi, Carl
, p. 2117 - 2125 (2007/10/02)
Allylpotassium derivatives were prepared from a variety of olefins by using Schlosser's base (BuLi/KOt-Bu).Reaction with (20S)-20-(iodomethyl)pregnane i-methyl ether (1) followed by deprotection gave in high yields a wide variety of Δ24 and Δ24(28) sterols, including the naturally occuring desmosterol (37), fucosterol (33), 24(E)-propylidenecholesterol (35), 24-methylenecholesterol (3), dehydroaplysterol (10), 25-methyl-24-methylenecholesterol (11), mutasterol (12), and 25-methylxestosterol (13).Control of the regiochemistry of unsymmetrical allylmetals was achieved through the addition of Li2CuCl3.Rules concerning the high regioselectivities and stereoselectivities are discussed.
