21089-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21089-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,8 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21089-34:
(7*2)+(6*1)+(5*0)+(4*8)+(3*9)+(2*3)+(1*4)=89
89 % 10 = 9
So 21089-34-9 is a valid CAS Registry Number.

New acetylated flavone C-glycosides from Iris lactea

Whaley, Andrei K.,Ebrahim, Weaam,El-Neketi, Mona,Ancheeva, Elena U.,?zkaya, Ferhat Can,Pryakhina, Nina I.,Sipkina, Nadezhda U.,Luzhanin, Vladimir G.,Liu, Zhen,Proksch, Peter

, p. 2171 - 2173 (2017)

Chemical investigation of the aerial parts of Iris lactea afforded three new flavone C-glycosides including 4?-O-acetyl-embinin (1), 2?,4?-O-diacetyl-embinin (2) and 6″,4?-O-diacetyl-embinin (3) along with the known analogue embinin (4). Their structures

ACYLATED C-GLYCOSIDES OF Iris lactea

Pryakhina, N. I.,Sheichenko, V. I.,Blinova, K. F.

, p. 554 - 559 (2007/10/02)

From the epigeal part of Iris lactea two acylated C-glycosylflavones not described in the literature have been isolated.On the basis of chemical transformations, and the results of UV, IR, and NMR spectroscopy, the following structures hyve been established for them: substance (I) - 5-hydroxy-4',7-dimethoxyflavone 6-C-2)-x-acetyl-β-D-glucopyranoside> (diacetylembinin); substance (II) - 5-hydroxy-4',7-dimethoxyflavone 6-C-2)-D-glucopyranoside> (acetylembinin).The existence of rotamers for 6-C-glucoflavones has been established for the first time.
