75569-35-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75569-35-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,6 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75569-35:
(7*7)+(6*5)+(5*5)+(4*6)+(3*9)+(2*3)+(1*5)=166
166 % 10 = 6
So 75569-35-6 is a valid CAS Registry Number.

Synthesis and absolute configuration of hylodiglyceride isolated from Hylodendron gabunensis

Wu, Wen-Ju,Chen, Hui-Jun,Wu, Yikang,Liu, Bo

, p. 92 - 96 (2014)

A recently isolated bismonoglyceride of heptadecanedioic acid, which represents a novel type of natural monoglycerides (i.e., with two instead of only one glycerol unit in the molecular architecture), was synthesized in enantiopure forms using a chiral-pool based approach with the 17-carbon chain constructed from undec-10-enoic acid and oct-7-en-1-ol via a cross metathesis and the stereogenic centers derived from (R)-(2,2-dimethyl-1,3-dioxolan-4-yl) methanol. An analogue with a longer alkyl chain was also synthesized. The synthetic samples not only allowed for establishment of the absolute configuration but also helped to reveal some minor yet unignorable errors in the 1H NMR data for the natural product. Optical rotation and NMR data acquired in DMSO and DMSO-d6, respectively, are also presented.
