<1-3H>Azulene, also known as 1,2,3,4,5,6,7,8-octahydroazulene, is a tritiated derivative of azulene, a bicyclic aromatic hydrocarbon with a unique structure consisting of a seven-membered ring fused to a five-membered ring. <1-3H>azulene is characterized by the presence of three tritium atoms (isotopes of hydrogen with two neutrons), which can be used for various applications in chemical research, such as tracing reactions or studying the behavior of molecules in different environments. Due to its radioactive nature, <1-3H>azulene must be handled with caution and proper safety measures.
The CAS Registry Mumber 935-89-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 935-89: (5*9)+(4*3)+(3*5)+(2*8)+(1*9)=97 97 % 10 = 7 So 935-89-7 is a valid CAS Registry Number.
