N2,N3-didechloroethylifosfamide, also known as cyclophosphamide, is a chemotherapeutic drug belonging to the nitrogen mustard class. It is an alkylating agent that is widely used in the treatment of various types of cancer, including lymphomas, leukemias, and solid tumors. Cyclophosphamide works by inhibiting DNA synthesis and function, ultimately leading to cell death. It is metabolized in the liver to produce active metabolites that are responsible for its cytotoxic effects. Due to its immunosuppressive properties, it is also used in the treatment of autoimmune diseases and as a conditioning regimen in bone marrow transplantation. However, it is associated with significant side effects, such as bone marrow suppression, bladder toxicity, and an increased risk of secondary malignancies.
The CAS Registry Mumber 5638-55-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,3 and 8 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5638-55: (6*5)+(5*6)+(4*3)+(3*8)+(2*5)+(1*5)=111 111 % 10 = 1 So 5638-55-1 is a valid CAS Registry Number.
