4767-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4767-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4767-67:
(6*4)+(5*7)+(4*6)+(3*7)+(2*6)+(1*7)=123
123 % 10 = 3
So 4767-67-3 is a valid CAS Registry Number.

FLAVONOIDS FROM Andrographis paniculata

Kuroyanagi, Masanori,Sato, Makoto,Ueno, Akira,Nishi, Kouzaburo

, p. 4429 - 4435 (2007/10/02)

A new flavanone glucoside, named andrographidine A (1), and five new flavone glucosides, named andrographidines B (2), C (3), D (4), E (5) and F (6), were isolated from the root of Andrographis paniculata.Their structures were determined on the basis of spectral data, especially carbon-13 and proton nuclear magnetic resonance spectra, and chemical derivatization.They have uncommon O-substitution patterns involving 5-, 7-, 8-, 2'-, 3'- and 4'-O-substituents.Keywords - Andrographis paniculata; Acanthaceae; flavone glucoside; flavanone glucoside; andrographidine A; Andrographidine B; 13C-NMR; methylglucopyranoside per-p-bromobenzoate; A-value
