821-17-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 821-17-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 821-17:
(5*8)+(4*2)+(3*1)+(2*1)+(1*7)=60
60 % 10 = 0
So 821-17-0 is a valid CAS Registry Number.

Fatty acid monomer, preparation method and thermoplastic macromolecule synthesized through application

-

Paragraph 0026, (2017/09/02)

The invention discloses a fatty acid monomer, a preparation method and a thermoplastic macromolecule synthesized through application. Tetramethyl guanidine and other catalysts are mainly utilized to catalyze a monomer containing halogen elements (Cl, Br and I) or halogen element and fatty acid, and the fatty acid monomer and thermoplastic macromolecule are obtained through efficient reaction. The application range can be thus widened by functionally improving the obtained fatty acid monomer and thermoplastic macromolecule. The reaction process is mild in condition, the catalytic efficiency of the catalysts is very high, few side reactions is produced, products are easy to separate and purify, and the fatty acid monomer and the thermoplastic macromolecule have a very high industrial application prospect.

Facile synthesis of lysophospholipids containing unsaturated fatty acid chains

Hopper, Darrin W.,Catalano, John G.,Macdonald, Timothy L.

, p. 7871 - 7874 (2007/10/03)

The efficient synthesis of polyunsaturated phospholipids is challenging due to the sensitivity of the unsaturated moiety to the conditions employed in phosphate ester deprotection. We discuss here three independent methods that resolve this issue and enable the synthesis of a series of unsaturated lysophosphatidic acid mimics for the development of a more comprehensive understanding of the structure-activity relationship in this series.
