42193-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42193-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,9 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42193-83:
(7*4)+(6*2)+(5*1)+(4*9)+(3*3)+(2*8)+(1*3)=109
109 % 10 = 9
So 42193-83-9 is a valid CAS Registry Number.

ANTIMICROBIAL AGENTS FROM HIGHER PLANTS: PRENYLATED FLAVONOIDS AND OTHER PHENOLS FROM GLYCYRRHIZA LEPIDOTA

Mitscher, Lester A.,Rao, G. S. Raghav,Khanna, Ish,Veysoglu, Tarik,Drake, Steven

, p. 573 - 576 (1983)

Bioassay directed fractionation of extracts of American licorice, Glycyrrhiza lepidota (Leguminosae), resulted in identification of the known bibenzyl, 3,5-dihydroxy-4-(3-methyl-2-butenyl)-bibenzyl, and the known flavones, glabranin and pinocembrin, as well as the isolation and structure determination of the new flavonol, glepidotin A and the new dihydroflavonol, glepidotin B as antimicrobial agents.Key Word - Glycyrrhiza lepidota; Leguminosae; prenylated flavones; biphenyls; antimicrobial activity.

1H-NMR CHEMICAL SHIFT OF THE FLAVONOL 5-HYDROXY PROTON AS A CHARACTERIZATION OF 6- OR 8-ISOPRENOID SUBSTITUTION

Fukai, Toshio,Nomura, Taro

, p. 1213 - 1225 (2007/10/02)

1H Nmr examination of 6- or 8-isoprenoid substituted flavonols has shown that the location of isoprenoid side chain on A ring can be deduced from the chemical shift of the 5-hydroxy proton.The application of this 1H nmr technique to identification of the
