103654-51-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103654-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,5 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 103654-51:
(8*1)+(7*0)+(6*3)+(5*6)+(4*5)+(3*4)+(2*5)+(1*1)=99
99 % 10 = 9
So 103654-51-9 is a valid CAS Registry Number.

Hormothamnione, a novel cytotoxic styrylchromone from the marine cyanophyte Hormothamnion enteromorphoides Grunow

Gerwick,Lopez,Van Duyne,et al.

, p. 1979 - 1982 (1986)

The first naturally occurring styrylchromone, hormothamnione, was isolated from the marine cyanophyte Hormothamnion enteromorphoides and its structure determined by an x-ray experiment on its triacetate derivative. Hormothamnione is an exceptionally potent cytotoxin to cancer cells in vitro and appears to be a selective inhibitor of RNA synthesis.

SYNTHESIS OF HORMOTHAMNIONE

Alonso, Ricardo,Brossi, Arnold

, p. 735 - 738 (2007/10/02)

Hormothamnione 1 has been obtained from 2,3-dimethyl-5,6,7,8-tetramethoxy-chromone 18 in 63percent yield.Synthesis of the required chromone 18 as well as of the 2 and 3-styryl analogs 5 and 9 are described.
