(3R,5R,6S)-6-(tert-Butyl-diphenyl-silanyloxymethyl)-3,5-dimethyl-tetrahydro-pyran-2-one is a complex organic compound with a molecular formula of C23H31O2Si. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the 3, 5, and 6 positions being R, R, and S, respectively. (3R,5R,6S)-6-(tert-Butyl-diphenyl-silanyloxymethyl)-3,5-dimethyl-tetrahydro-pyran-2-one features a tetrahydro-pyran-2-one ring, which is a type of cyclic ether, and a silyl ether group, which is a protecting group often used in organic synthesis. The tert-butyl-diphenyl-silanyloxymethyl group is a bulky, electron-donating substituent that can influence the reactivity and selectivity of the molecule. (3R,5R,6S)-6-(tert-Butyl-diphenyl-silanyloxymethyl)-3,5-dimethyl-tetrahydro-pyran-2-one may be used in the synthesis of more complex organic molecules, particularly in the field of pharmaceuticals or materials science, where its unique structure and properties can be exploited for specific chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 81669-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,6 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81669-01:
(7*8)+(6*1)+(5*6)+(4*6)+(3*9)+(2*0)+(1*1)=144
144 % 10 = 4
So 81669-01-4 is a valid CAS Registry Number.
