13909-16-5 Usage
General Description
1-(2-chloroethyl)-3-(2,3-dihydro-1H-inden-2-yl)-1-nitrosourea, also known as lomustine, is a chemotherapeutic agent used in the treatment of various types of cancer, including brain tumors, melanoma, and Hodgkin's lymphoma. It belongs to the class of nitrosoureas and works by inhibiting DNA and RNA synthesis in cancer cells, ultimately leading to their death. Lomustine is administered orally and is able to cross the blood-brain barrier, making it particularly effective in treating brain tumors. However, it can cause serious side effects such as bone marrow suppression, liver toxicity, and pulmonary fibrosis, and therefore should be used with caution under the supervision of a healthcare professional. Its use in cancer therapy is still under investigation, and ongoing research aims to further understand its mechanisms of action and potential applications in different types of cancer.
Check Digit Verification of cas no
The CAS Registry Mumber 13909-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,0 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13909-16:
(7*1)+(6*3)+(5*9)+(4*0)+(3*9)+(2*1)+(1*6)=105
105 % 10 = 5
So 13909-16-5 is a valid CAS Registry Number.
