90762-99-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90762-99-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,6 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90762-99:
(7*9)+(6*0)+(5*7)+(4*6)+(3*2)+(2*9)+(1*9)=155
155 % 10 = 5
So 90762-99-5 is a valid CAS Registry Number.

Thermal Degradation of Glycosides, VI - Hydrothermolysis of Cardenolide and Flavonoid Glycosides

Kim, Youn Chul,Higuchi, Ryuichi,Komori, Tetsuya

, p. 575 - 580 (2007/10/02)

The hydrothermolysis of cardenolide and flavonoid glycosides is described.On heating with water or water/dioxane, cardenolide (1, 5, 11) and flavonoid glycosides (16, 20, 23, 27) are converted into their genuine aglycones and partially hydrolyzed products, together with saccharide components.Meanwhile, the glycosidic linkage of 2-deoxy sugar moieties in cardenolide glycosides is more readily cleaved than that of the common sugar moieties by means of hydrothermolysis.Therefore, hydrothermolysis of the uzarigenin triglycoside (13), bearing a 2-deoxy sugar moiety whichis directly attached to the aglycone, leads to selective cleavage of the sugar-aglycone linkage.The hydrothermolyzed products have been isolated by chromatography and their structures elucidated by spectroscopic methods.
