(2R,3R)-3,5-dimethyl-2-phenyl-2,3-dihydro-4H-pyran-4-one is a complex organic compound with a molecular formula of C14H14O3. It is a chiral molecule, meaning it has a non-superimposable mirror image, and the specific configuration is indicated by the (2R,3R) notation. (2R,3R)-3,5-dimethyl-2-phenyl-2,3-dihydro-4H-pyran-4-one features a pyran ring, which is a six-membered oxygen-containing ring, and a phenyl group attached to the second carbon. The molecule also has two methyl groups at the third and fifth positions, respectively. It is a dihydro derivative, indicating that it has two hydrogen atoms fewer than the fully unsaturated parent compound. This chemical is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of more complex molecules or as a component in various chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 88198-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,9 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88198-71:
(7*8)+(6*8)+(5*1)+(4*9)+(3*8)+(2*7)+(1*1)=184
184 % 10 = 4
So 88198-71-4 is a valid CAS Registry Number.
