The chemical compound "(3aR)-6-acetoxy-5-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl)-2-phenyl-(3aR,6aα)-3a,6a-dihydro-furo[3,2-d]oxazole" is a complex organic molecule with a unique structure. It features a furo[3,2-d]oxazole ring, which is a type of heterocyclic compound with a furan ring fused to an oxazole ring. The compound has a 3a,6a-dihydro configuration, indicating that there are two hydrogen atoms attached to the 3a and 6a positions, which are part of the dihydro structure. It also contains a phenyl group attached to the 2-position and a 2,2-dimethyl-[1,3]dioxolan-4-yl group at the 5-position, which is a substituted dioxolane ring. The 6-position is substituted with an acetoxy group, which is an acetate ester of a hydroxyl group. The compound's stereochemistry is specified by the 'R' configuration at both the 3a and 5 positions, indicating that the substituents at these positions are arranged in a specific three-dimensional orientation. (3aR)-6-acetoxy-5-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl)-2-phenyl-(3ar,6ac)-3a,6a-dihydro-furo[3,2-d]oxazole is likely to be of interest in the field of organic chemistry, potentially for its unique reactivity or as a building block in the synthesis of more complex molecules.
The CAS Registry Mumber 19949-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,4 and 9 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 19949-69: (7*1)+(6*9)+(5*9)+(4*4)+(3*9)+(2*6)+(1*9)=170 170 % 10 = 0 So 19949-69-0 is a valid CAS Registry Number.
