**1,3-Dioxolan-4-one, 5-phenyl-, (S)-** is a chiral dioxolanone derivative featuring a phenyl substituent at the 5-position. It serves as a key intermediate in enantioselective syntheses, such as the production of (3S,4S)-3-hydroxy-4-phenylbutyrolactone, via nonclassical Wittig reactions. 1,3-Dioxolan-4-one, 5-phenyl-, (S)-'s optical activity and conformational behavior (e.g., equilibrium between envelope and planar forms) influence its circular dichroism properties, as described by Weigang's sector rules. Its stereochemistry and reactivity make it valuable for constructing complex chiral lactones. (Other names for 1,3-Dioxolan-4-one, 5-phenyl-, (S)- are not provided in the abstracts.)

60646-33-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60646-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,6,4 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 60646-33:
(7*6)+(6*0)+(5*6)+(4*4)+(3*6)+(2*3)+(1*3)=115
115 % 10 = 5
So 60646-33-5 is a valid CAS Registry Number.
