((2R,3R,4S,5R)-4,5-Bis-benzyloxy-2-methoxy-tetrahydro-pyran-3-yloxy)-trimethyl-silane is a complex organic compound with the molecular formula C23H32O5Si. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the R configuration at the 2nd, 3rd, and 5th carbon atoms, and the S configuration at the 4th carbon atom. The compound features a tetrahydro-pyran ring, which is a type of cyclic ether, and is substituted with two benzyloxy groups at the 4th and 5th positions, a methoxy group at the 2nd position, and a trimethylsilyl group at the 3-yloxy position. ((2R,3R,4S,5R)-4,5-Bis-benzyloxy-2-methoxy-tetrahydro-pyran-3-yloxy)-trimethyl-silane is often used in organic synthesis, particularly in the protection of hydroxyl groups due to the stability of the silyl ether. The trimethylsilyl group can be easily removed under mild acidic conditions, making it a useful protecting group in various chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 87461-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,6 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87461-47:
(7*8)+(6*7)+(5*4)+(4*6)+(3*1)+(2*4)+(1*7)=160
160 % 10 = 0
So 87461-47-0 is a valid CAS Registry Number.
