Methemoglobin, also known as ferric hemoglobin, is a form of hemoglobin in which the iron is oxidized from the ferrous (Fe2+) to the ferric (Fe3+) state. This oxidation impairs the molecule's ability to bind and transport oxygen effectively, leading to reduced oxygen-carrying capacity in the blood. Methemoglobinemia, the condition characterized by elevated levels of methemoglobin, can result from genetic mutations, exposure to certain chemicals or drugs, or other factors that cause the oxidation of hemoglobin. Symptoms may include cyanosis, fatigue, and shortness of breath, and treatment may involve the administration of methylene blue or other reducing agents to convert methemoglobin back to its functional form.
The CAS Registry Mumber 9008-37-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 8 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 9008-37: (6*9)+(5*0)+(4*0)+(3*8)+(2*3)+(1*7)=91 91 % 10 = 1 So 9008-37-1 is a valid CAS Registry Number.
