(2,3E)-2,3-dideoxy-4,5;6,7-di-O-isopropylidene-aldehydo-D-arabino-hept-2-enose is a complex organic compound with a unique structure. It is a derivative of D-arabino-hept-2-enose, a monosaccharide, with specific modifications. The compound features a 2,3-dideoxy modification, which means that the hydroxyl groups at the 2nd and 3rd carbon atoms are missing. Additionally, it has an aldehydo group, indicating the presence of a carbonyl group at the terminal carbon. The 4,5 and 6,7 positions are di-O-isopropylidene, which means that two hydroxyl groups are each protected by an isopropylidene group, a common protecting group in organic chemistry that prevents unwanted reactions at these positions. The E configuration at the 2,3 double bond indicates the geometric arrangement of the double bond. (2,3E)-2,3-dideoxy-4,5;6,7-di-O-isopropylidene-aldehydo-D-arabino-hept-2-enose is significant in the field of organic chemistry, particularly in the synthesis of complex carbohydrates and as a potential intermediate in the preparation of various biologically active molecules.

4640-90-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4640-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4640-90:
(6*4)+(5*6)+(4*4)+(3*0)+(2*9)+(1*0)=88
88 % 10 = 8
So 4640-90-8 is a valid CAS Registry Number.
