Actinomycin I, also known as dactinomycin, is a naturally occurring cytotoxic antibiotic derived from the bacterium Streptomyces parvulus. It is a member of the actinomycin family of compounds, characterized by a cyclic peptide structure with a phenoxazone chromophore. Actinomycin I is known for its antineoplastic properties, as it intercalates into DNA, inhibiting RNA synthesis and ultimately leading to cell death. It has been used in the treatment of various cancers, particularly Wilms' tumor and Ewing's sarcoma, and is also employed as a research tool to study DNA-protein interactions. The compound's mechanism of action involves binding to the guanine-cytosine rich regions of DNA, which disrupts the DNA's double helix structure and interferes with the transcription process.
The CAS Registry Mumber 1402-60-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,0 and 2 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1402-60: (6*1)+(5*4)+(4*0)+(3*2)+(2*6)+(1*0)=44 44 % 10 = 4 So 1402-60-4 is a valid CAS Registry Number.
