Ricin is a highly toxic protein derived from the seeds of the castor oil plant, Ricinus communis. It is a potent inhibitor of protein synthesis, as it inactivates ribosomes, leading to cell death. Ricin is considered a dangerous biological toxin due to its stability, ease of production, and potential for causing severe harm or death in small quantities. It can be delivered through various means, including ingestion, inhalation, or injection, and has been a subject of interest for its potential use in bioterrorism. Despite its lethal properties, ricin has also been studied for potential therapeutic applications, such as targeted cancer treatments, due to its ability to selectively destroy cancer cells.
The CAS Registry Mumber 9067-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,6 and 7 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 9067-26: (6*9)+(5*0)+(4*6)+(3*7)+(2*2)+(1*6)=109 109 % 10 = 9 So 9067-26-9 is a valid CAS Registry Number.
