The chemical compound "(6R)-7t,8c-diacetoxy-7,8,9,10-tetrahydro-6H-6r,9c-epoxido-pyrimido[2,1-b][1,3]oxazocin-2-one" is a complex organic molecule with a unique structure. It features a pyrimido[2,1-b][1,3]oxazocin-2-one core, which is a fused ring system consisting of a pyrimidine and an oxazocine. The compound is characterized by a 6H-6r,9c-epoxide bridge, indicating the presence of an epoxide group, which is a three-membered ring consisting of two carbon atoms and one oxygen atom. Additionally, it has a tetrahydro-7,8,9,10 structure, suggesting the presence of four hydrogen atoms in the molecule. The 7t,8c-diacetoxy groups indicate that there are two acetoxy groups attached to the molecule, one at the 7th and the other at the 8th carbon positions. The "6R" notation specifies the configuration of the molecule at the 6th carbon, indicating that it is in the R configuration. (6R)-7t,8c-diacetoxy-7,8,9,10-tetrahydro-6H-6r,9c-epioxido-pyrimido[2,1-b][1,3]oxazocin-2-one is likely to be of interest in the field of organic chemistry, potentially for its unique reactivity or biological activity.
The CAS Registry Mumber 7374-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,7 and 4 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7374-81: (6*7)+(5*3)+(4*7)+(3*4)+(2*8)+(1*1)=114 114 % 10 = 4 So 7374-81-4 is a valid CAS Registry Number.
