(3S,4S)-3,4-Dimethyl-azetidin-2-one is a chiral cyclic amide with the molecular formula C6H11NO. It features a four-membered azetidine ring, with two methyl groups at the 3rd and 4th positions, and a carbonyl group at the 2nd position. (3S,4S)-3,4-Dimethyl-azetidin-2-one is an important building block in organic synthesis, particularly for the preparation of various pharmaceuticals and natural products. Its chirality arises from the two stereocenters at the 3rd and 4th positions, which can exist in either the R or S configuration. The specific (3S,4S) configuration indicates that both chiral centers have the S configuration, which is crucial for its reactivity and potential applications in the synthesis of enantiomerically pure compounds.

6789-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6789-97-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,8 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.Calculate Digit Verification of CAS Registry Number 6789-97:
(6*6)+(5*7)+(4*8)+(3*9)+(2*9)+(1*7)=155
155 % 10 = 5
So 6789-97-5 is a valid CAS Registry Number.
