19485-76-8 Usage
General Description
Cholesteryl elaidate is a chemical compound that belongs to the family of cholesteryl esters, which are formed by the esterification of cholesterol with a specific type of fatty acid called elaidic acid. It is commonly used in the food industry as a source of cholesterol, often found in processed foods like margarine, baked goods, and snack foods. Cholesteryl elaidate is known to have a significant impact on blood cholesterol levels and has been linked to an increased risk of heart disease. Its consumption has been a topic of controversy due to its potential negative health effects, especially in the context of a high-fat diet.
Check Digit Verification of cas no
The CAS Registry Mumber 19485-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,8 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19485-76:
(7*1)+(6*9)+(5*4)+(4*8)+(3*5)+(2*7)+(1*6)=148
148 % 10 = 8
So 19485-76-8 is a valid CAS Registry Number.

Palladium(II)-catalyzed meta-selective C?H allylation of arenes has been developed utilizing synthetically inert unactivated acyclic internal olefins as allylic surrogates. The strong σ-donating and π-accepting ability of pyrimidine-based directing group facilitates the olefin insertion by overcoming inertness of the typical unactivated internal olefins. Exclusive allyl over styrenyl product selectivity as well as E stereoselectivity were achieved with broad substrate scope, wide functional-group tolerance, and good to excellent yields. Late-stage functionalisations of pharmaceuticals were demonstrated. Experimental and computational studies shed light on the mechanism and point to key steric control in the palladacycle, thus determining product selectivities.
