1026565-45-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1026565-45-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,5,6 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1026565-45:
(9*1)+(8*0)+(7*2)+(6*6)+(5*5)+(4*6)+(3*5)+(2*4)+(1*5)=136
136 % 10 = 6
So 1026565-45-6 is a valid CAS Registry Number.

Free-radical-mediated conjugate additions. Enantioselective synthesis of butyrolactone natural products: (-)-Enterolactone, (-)-arctigenin, (-)-isoarctigenin, (-)-nephrosteranic acid, and (-)-roccellaric acid

Sibi, Mukund P.,Liu, Pingrong,Ji, Jianguo,Hajra, Saumen,Chen, Jian-Xie

, p. 1738 - 1745 (2007/10/03)

Lewis acid-mediated conjugate addition of alkyl radicals to a differentially protected fumarate 10 produced the monoalkylated succinates with high chemical efficiency and excellent stereoselectivity. A subsequent alkylation or an aldol reaction furnished the disubstituted succinates with syn configuration. The chiral auxiliary, 4-diphenylmethyl-2-oxazolidinone, controlled the stereoselectivity in both steps. Manipulation of the disubstituted succinates obtained by alkylation furnished the natural products (-)-enterolactone, (-)-arctigenin, and (-)-isoarctigenin. The overall yields for the target natural products were 20-26% over six steps. Selective functionalization of the disubstituted succinates obtained by aldol condensation gave the paraconic acid natural products (-)-nephrosteranic acid (8) and (-)-roccellaric acid (9). The overall yield of the natural products 8 and 9 over four steps was 53% and 42%, respectively.
