Erabutoxin B is a potent neurotoxin derived from the venom of the Laticauda colubrina, also known as the sea krait. It primarily targets the nicotinic acetylcholine receptors (nAChRs) in the neuromuscular junction, leading to paralysis and respiratory failure. The toxin is composed of 60 amino acid residues and has a molecular weight of approximately 7 kDa. Erabutoxin B is known for its high affinity and specificity for the α3β2 subtype of nAChRs, making it a valuable tool in studying the structure and function of these receptors. Due to its toxicity, it has also been investigated for potential therapeutic applications, such as in the development of analgesics and as a research tool in neurobiology.
The CAS Registry Mumber 9083-23-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,8 and 3 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 9083-23: (6*9)+(5*0)+(4*8)+(3*3)+(2*2)+(1*3)=102 102 % 10 = 2 So 9083-23-2 is a valid CAS Registry Number.
