DL-erythro-Methyl-3-(3-methyl-4,5-diphenyl-pentan-3,4-diol-2,5-dion)-cyclophosphat, also known as Troger's base, is a complex organic compound with the molecular formula C19H21O5P. It is a key intermediate in the synthesis of various phosphorus-containing compounds, particularly in the production of cyclophosphamide, a widely used alkylating agent in cancer chemotherapy. Troger's base is synthesized through a series of chemical reactions involving the condensation of formaldehyde, acetone, and phosphorus trichloride, followed by hydrolysis and methylation. Its structure features a cyclophosphamide core with a methyl group attached to the phosphorus atom, and a 3-methyl-4,5-diphenyl-pentan-3,4-diol-2,5-dione moiety. Due to its importance in pharmaceutical chemistry, Troger's base has been extensively studied for its chemical properties, reactivity, and potential applications in drug development.
The CAS Registry Mumber 5848-81-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 8 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5848-81: (6*5)+(5*8)+(4*4)+(3*8)+(2*8)+(1*1)=127 127 % 10 = 7 So 5848-81-7 is a valid CAS Registry Number.
