Protodyne, also known as protactinium-233, is a radioactive isotope of protactinium with the chemical symbol Pa and atomic number 91. It is a fissile material, meaning it can sustain a nuclear chain reaction, and is primarily produced as a byproduct of uranium-233 decay in nuclear reactors. Protodyne has a half-life of approximately 27 days, making it a short-lived isotope. Due to its radioactivity and potential use in nuclear technology, it is a subject of interest in the fields of nuclear energy and weapons development. However, its handling and use require strict safety measures and regulatory oversight due to its potential hazards and applications.
The CAS Registry Mumber 9050-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,5 and 0 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 9050-79: (6*9)+(5*0)+(4*5)+(3*0)+(2*7)+(1*9)=97 97 % 10 = 7 So 9050-79-7 is a valid CAS Registry Number.
