Check Digit Verification of cas no

The CAS Registry Mumber 5143-08-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5143-08:
(6*5)+(5*1)+(4*4)+(3*3)+(2*0)+(1*8)=68
68 % 10 = 8
So 5143-08-8 is a valid CAS Registry Number.

Crenulacetal C, a marine diterpene, and its synthetic mimics inhibiting Polydora websterii, a harmful lugworm damaging pearl cultivation

Polydora websterii, a harmful lugworm that has serious adverse effects on pearl oyster cultivation, was inhibited by a marine diterpene, crenulacetal C, isolated from the brown alga Dictyota dichotoma. Based on consideration of the activity-structure relationship, several synthetic compounds having an aromatic moiety with a hydroxyalkyl chain were prepared. Bioassay using larvae of Polydora websterii as well as pearl oysters (Pinctada fucata martians) suggested that 1-(2-ferrule)-1-nonanol was the most promising inhibitor.
