Hemoglobin Hirose, also known as hemoglobin A2, is a variant of the hemoglobin molecule that plays a crucial role in oxygen transport within the human body. It is composed of two alpha and two delta globin chains, making it distinct from the more common hemoglobin A, which consists of two alpha and two beta chains. Hemoglobin Hirose is present in small amounts in adult red blood cells, typically accounting for about 2-3% of the total hemoglobin. It has a higher affinity for oxygen compared to hemoglobin A, which allows it to efficiently pick up oxygen in the lungs and release it in tissues with lower oxygen concentrations. This characteristic makes hemoglobin Hirose an essential component in maintaining proper oxygen levels in the body.
The CAS Registry Mumber 9066-26-6 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 6 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 9066-26: (6*9)+(5*0)+(4*6)+(3*6)+(2*2)+(1*6)=106 106 % 10 = 6 So 9066-26-6 is a valid CAS Registry Number.
