"10-(tert-Butyl-diphenyl-silanyloxy)-deca-5,8-diynoic acid methyl ester" is a complex organic compound with the molecular formula C23H26O3Si. It is characterized by a deca-5,8-diynoic acid backbone, which features two carbon-carbon triple bonds at the 5th and 8th positions, separated by a single carbon atom. The molecule is further modified by a tert-butyl-diphenyl-silanyloxy group at the 10th position, which introduces a bulky, electron-donating silyl ether moiety. This group can influence the molecule's reactivity and stability. The methyl ester functional group at the carboxylic acid end provides a more stable and less reactive form of the acid, which can be useful in certain chemical reactions and applications. 10-(tert-Butyl-diphenyl-silanyloxy)-deca-5,8-diynoic acid methyl ester is likely to be used in advanced organic synthesis, potentially in the preparation of pharmaceuticals or materials science, due to its unique structure and reactivity.
The CAS Registry Mumber 98050-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,5 and 0 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 98050-18: (7*9)+(6*8)+(5*0)+(4*5)+(3*0)+(2*1)+(1*8)=141 141 % 10 = 1 So 98050-18-1 is a valid CAS Registry Number.
