Check Digit Verification of cas no

The CAS Registry Mumber 325151-62-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,5,1,5 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 325151-62:
(8*3)+(7*2)+(6*5)+(5*1)+(4*5)+(3*1)+(2*6)+(1*2)=110
110 % 10 = 0
So 325151-62-0 is a valid CAS Registry Number.

Turbotoxins A and B, novel diiodotyramine derivatives from the Japanese gastropod Turbo marmorata

Kigoshi, Hideo,Kanematsu, Kengo,Yokota, Kyoko,Uemura, Daisuke

, p. 9063 - 9070 (2007/10/03)

Bioassay-guided separation of the aqueous ethanol extract of the viscera of the Japanese gastropod Turbo marmorata resulted in the isolation of two toxins, turbotoxins A and B. Their structures were determined by spectral analysis and confirmed by organic synthesis to be diiodotyramine derivatives. Turbotoxins A and B exhibited acute toxicity against ddY mice, with LD99 values of 1.0 and 4.0 mg/kg, respectively. The structure-toxicity relationships of turbotoxins were examined, and it was proved that the iodine atoms and trimethylammonium groups are important for its acute toxicity. Turbotoxin A inhibits acetylcholinesterase with an IC50 of 28 μM. (C) 2000 Elsevier Science Ltd.
