Tetrodotoxin (TTX) is a potent neurotoxin found primarily in the pufferfish, as well as in certain species of frogs, shellfish, and other marine animals. It is a small, water-soluble molecule that acts by blocking voltage-gated sodium channels in nerve cells, thereby inhibiting the transmission of nerve impulses and leading to paralysis and potentially death. TTX is one of the most toxic non-protein substances known, with a lethal dose for humans estimated to be around 2 milligrams. Due to its potency, TTX has been the subject of extensive research for its potential applications in medicine, such as pain management and neurobiology, despite its inherent dangers.
The CAS Registry Mumber 2244-58-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 4 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2244-58: (6*2)+(5*2)+(4*4)+(3*4)+(2*5)+(1*8)=68 68 % 10 = 8 So 2244-58-8 is a valid CAS Registry Number.
