Check Digit Verification of cas no
The CAS Registry Mumber 22273-47-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,7 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22273-47:
(7*2)+(6*2)+(5*2)+(4*7)+(3*3)+(2*4)+(1*7)=88
88 % 10 = 8
So 22273-47-8 is a valid CAS Registry Number.

Preparation of naphthoquinone derivatives from plumbagin and their ichthyotoxicity
Ogihara, Kazuhito,Yamashiro, Rieko,Higa, Matsutake,Yogi, Seiichi
, p. 437 - 445 (2007/10/03)
Various naphthoquinone derivatives were prepared from a natural product, 5-hydroxy-2-methyl-1,4-naphthoquinone (plumbagin); these were mostly substituted at C-3 through carbon-carbon bond formation mediated by a metal- based oxidant such as lead tetraacetate in the presence of various carboxylic acids. The halogenated compounds showed stronger ichthyotoxicity than plumbagin, but other derivatives were less active.
