2,5-dimethyl-3,4-bis-trimethylsilanyloxy-hex-3-ene is a complex organic compound with the molecular formula C13H28OSi2. It features a hexene backbone, with two methyl groups at the 2nd and 5th carbon positions, and two trimethylsilanyloxy groups attached to the 3rd and 4th carbon positions. The trimethylsilanyloxy groups consist of a silicon atom bonded to three methyl groups and an oxygen atom, which in turn is bonded to the carbon atoms in the hexene chain. 2,5-dimethyl-3,4-bis-trimethylsilanyloxy-hex-3-ene is known for its stability and is often used in organic synthesis as a protecting group for alcohols, as the trimethylsilanyloxy groups can be easily removed under acidic conditions to regenerate the alcohol. Its unique structure also makes it a subject of interest in the study of organosilicon chemistry and as a potential intermediate in the synthesis of more complex molecules.
The CAS Registry Mumber 6838-61-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,3 and 8 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6838-61: (6*6)+(5*8)+(4*3)+(3*8)+(2*6)+(1*1)=125 125 % 10 = 5 So 6838-61-5 is a valid CAS Registry Number.
