Bence Jones protein, also known as immunoglobulin light chains, are a type of protein produced by abnormal plasma cells in the bone marrow. These proteins are a key component of antibodies and are typically excreted in the urine when produced in excess, a condition known as Bence Jones proteinuria. This can be indicative of certain diseases, such as multiple myeloma, a type of cancer that affects plasma cells. Bence Jones proteins are composed of two types of light chains, kappa and lambda, which can be identified and quantified through laboratory tests to aid in the diagnosis and monitoring of related disorders.
The CAS Registry Mumber 9006-99-9 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 6 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 9006-99: (6*9)+(5*0)+(4*0)+(3*6)+(2*9)+(1*9)=99 99 % 10 = 9 So 9006-99-9 is a valid CAS Registry Number.
