((2R,3R,6S)-6-Methoxy-3,5-dimethyl-2-phenyl-3,6-dihydro-2H-pyran-4-yloxy)-trimethyl-silane is a complex organic compound with the molecular formula C18H28O3Si. It features a 3,6-dihydro-2H-pyran ring structure, which is a type of cyclic ether, with a 6-methoxy group, 3,5-dimethyl substituents, and a 2-phenyl group. The compound also has a trimethylsilyl group attached to the 4-hydroxyl position of the pyran ring. This specific arrangement of functional groups and stereochemistry gives the molecule unique chemical properties and reactivity. It is typically used in organic synthesis, particularly in reactions where the trimethylsilyl group can be used to protect hydroxyl groups or as a part of a silyl ether protecting group. The compound's chirality is indicated by the (2R,3R,6S) configuration, which specifies the three-dimensional arrangement of atoms at the chiral centers.
The CAS Registry Mumber 85613-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,1 and 3 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 85613-11: (7*8)+(6*5)+(5*6)+(4*1)+(3*3)+(2*1)+(1*1)=132 132 % 10 = 2 So 85613-11-2 is a valid CAS Registry Number.
