79580-28-2 Usage
Description
Brevetoxin B is a polyketide neurotoxin produced by Karenia species and other dinoflagellates. It binds to site 5 on the alpha subunit of voltage-gated sodium channels (IC50 = 15 nM) on neurons at the neuromuscular junction, causing the channel to open irreversibly at potentials more negative than normal, discharging action potentials repetitively. Brevetoxin B is ichthyotoxic at nanomolar concentrations and is responsible for an illness described as neurotoxic shellfish poisoning.
Check Digit Verification of cas no
The CAS Registry Mumber 79580-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,5,8 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79580-28:
(7*7)+(6*9)+(5*5)+(4*8)+(3*0)+(2*2)+(1*8)=172
172 % 10 = 2
So 79580-28-2 is a valid CAS Registry Number.
