10-methoxy-5,10-dihydro-phenarsazine is a chemical compound with the molecular formula C12H13AsO2N2. It is a derivative of phenarsazine, a heterocyclic compound containing arsenic, carbon, hydrogen, nitrogen, and oxygen. This specific compound features a methoxy group (-OCH3) at the 10th position and a dihydro (reduced) structure, which means it has two hydrogen atoms added to the phenarsazine ring. The compound is of interest in the field of organoarsenic chemistry and may have potential applications in various chemical and pharmaceutical industries. However, due to the presence of arsenic, it is essential to handle 10-methoxy-5,10-dihydro-phenarsazine with caution, as arsenic-containing compounds can be toxic.
The CAS Registry Mumber 4808-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,0 and 8 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4808-21: (6*4)+(5*8)+(4*0)+(3*8)+(2*2)+(1*1)=93 93 % 10 = 3 So 4808-21-3 is a valid CAS Registry Number.
