10-(4,5-Dimethoxy-2-methyl-3,6-dioxo-cyclohexa-1,4-dienyl)-decanoic acid tert-butyl ester is a complex organic compound with the molecular formula C20H32O6. It is a derivative of decanoic acid, featuring a cyclohexa-1,4-dienyl moiety with a 2-methyl group and two methoxy groups at the 4 and 5 positions, respectively. The molecule also contains a tert-butyl ester group, which is a bulky, sterically hindered ester that can protect the carboxylic acid group from unwanted reactions. 10-(4,5-Dimethoxy-2-methyl-3,6-dioxo-cyclohexa-1,4-dienyl)-decanoic acid tert-butyl ester is likely used in chemical synthesis, particularly in the preparation of pharmaceuticals or other complex organic molecules, due to its unique structural features and reactivity.
The CAS Registry Mumber 84978-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,7 and 8 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 84978-08: (7*8)+(6*4)+(5*9)+(4*7)+(3*8)+(2*0)+(1*8)=185 185 % 10 = 5 So 84978-08-5 is a valid CAS Registry Number.
