(2S,3E,5S)-1,2,5,6-tetrahydroxy-1,2:5,6-di-O-isopropylidene-hex-3-ene is a complex organic compound characterized by its unique stereochemistry and functional groups. It features a hexene backbone with a double bond between the 3rd and 4th carbon atoms (3E), and hydroxyl groups at the 1st, 2nd, 5th, and 6th carbon positions. The compound is further modified by the presence of isopropylidene groups bridging the hydroxyl groups at the 1st and 2nd, as well as the 5th and 6th carbons, which protect these hydroxyl groups from further reactions. The stereochemistry at the 2nd and 5th carbons is in the S configuration, indicating that the hydroxyl groups are on the same side of the molecule when viewed along the bond connecting these carbons. (2S,3E,5S)-1,2,5,6-tetrahydroxy-1,2:5,6-di-O-isopropylidene-hex-3-ene is of interest in organic chemistry, particularly in the synthesis of complex molecules and the study of stereochemistry.
The CAS Registry Mumber 3427-24-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,2 and 7 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3427-24: (6*3)+(5*4)+(4*2)+(3*7)+(2*2)+(1*4)=75 75 % 10 = 5 So 3427-24-5 is a valid CAS Registry Number.
