Check Digit Verification of cas no

The CAS Registry Mumber 679431-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,9,4,3 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 679431-81:
(8*6)+(7*7)+(6*9)+(5*4)+(4*3)+(3*1)+(2*8)+(1*1)=203
203 % 10 = 3
So 679431-81-3 is a valid CAS Registry Number.

Novel Caprolactones from a Marine Streptomycete

Stritzke, Katja,Schulz, Stefan,Laatsch, Hartmut,Helmke, Elisabeth,Beil, Winfried

, p. 395 - 401 (2007/10/03)

Two new caprolactones, (R)-10-methyl-6-undecanolide (1) and (6R,10S)-10-methyl-6-dodecanolide (2), were identified in the lipid extract of a marine streptomycete (isolate B6007). Their structures were proposed on the basis of GC-MS experiments and proved by synthesis. The absolute configuration of the compounds was established by comparison of the natural and synthetic stereoisomers using chiral gas chromatography. These caprolactones show a moderate phytotoxicity and a promising activity against cancer cells with concomitant low general cytotoxicity.
