Check Digit Verification of cas no

The CAS Registry Mumber 104840-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,4 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104840-56:
(8*1)+(7*0)+(6*4)+(5*8)+(4*4)+(3*0)+(2*5)+(1*6)=104
104 % 10 = 4
So 104840-56-4 is a valid CAS Registry Number.

Metabolites produced by the Scleroderris canker fungus, Gremmeniella abietina. Part 1

Ayer, William A.,Hoyano, Yumiko,Pedras, M. Soledade,van Altena, Ian

, p. 1585 - 1589 (2007/10/02)

The metabolites produced in liquid culture by the Ascomycetous fungus Gremmeniella abietina (Lagerb.).Morelet, the causative agent of Scleroderris canker in pines, have been investigated.The major metabolite, which we have named sclerodin, is (-)-4,7-dihydroxy-2,3,3,9-tetramethyl-2,3-dihydronaphthofuran-5,6-dicarboxylic anhydride (1), the enantiomer of the so-called "naphthalic anhydride from atrovenetin".Several highly colored compounds, including the enantiomer of atrovenetinone (3), the blue compound 6, the red acenaphthenequinone derivative 8 (sclerodione), and the yellow 8-hydroxysclerodione (8) has been transformed into sclerodin (1).
