39701-13-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39701-13-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,0 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39701-13:
(7*3)+(6*9)+(5*7)+(4*0)+(3*1)+(2*1)+(1*3)=118
118 % 10 = 8
So 39701-13-8 is a valid CAS Registry Number.

STRUCTURE DETERMINATION OF MELANERVIN, THE FIRST NATURALLY OCCURING FLAVONOID OF THE TRIPHENYLMETHANE FAMILY

Seligmann, O.,Wagner, H.

, p. 2601 - 2606 (1981)

From the flowers of Melaleuca quinquenervia (Myrtaceae) besides the flavonones strobopinin and kryptostrobin a new 8-aryl-flavonone has been isolated and shown to be (2,4-dihydroxy-6-methoxy)tolyl-3-(5,7-dihydroxy-6-methyl)flavanonyl-8-phenylmethane, mainly by degradation, MS, 1H- and 13C-NMR-spectroscopy.The new flavanone represents the first naturally occuring triphenylmethane compound.

Efficient synthesis of rottlerin and its two subunits

Li, Yangfeng,Yu, Biao,Wang, Renxiao

, p. 1856 - 1859 (2016/04/19)

Rottlerin, a natural product isolated from Mallotus philippensis, is associated with a range of biological activities. Its chemical structure is featured by two different substituted phloroglucinol units linked by a methylene group. In this study, we accomplished a total synthesis of rottlerin using phenol-aldehyde condensation as the key reaction. By our method, gram-scale preparation of the two structural subunits was achieved, and rottlerin was obtained in a longest eight linear step with 20% overall yield. Our study provides a practical solution for obtaining the sample of rottlerin in an efficient way.

Synthesis of aurentiacin

Hossain, M. Amzad

, p. 324 - 326 (2007/10/03)

Aurentiacin 7 has been isolated from Pityrogramma triangularis var. pallida and synthesised from phloroacetophenone 1 in several steps. All the new products have been characterised on the basis of spectral data and micro analysis.
