7,8-dideoxy-1,2:3,4-di-O-isopropylidene-α-D-glycero-D-galacto-hept-7-enopyranose is a complex organic compound belonging to the class of carbohydrates. It is a modified sugar molecule, specifically a heptose (seven-carbon sugar) derivative, with a double bond at the seventh position. The compound features a 1,2:3,4-di-O-isopropylidene protecting group, which consists of two isopropylidene groups attached to the hydroxyl groups at the first and second, as well as the third and fourth carbon atoms. This protection is crucial for preventing unwanted side reactions during chemical synthesis. The α-D-glycero-D-galacto configuration indicates the stereochemistry of the molecule, with the hydroxyl groups at the second and third carbon atoms being in the α-configuration. 7,8-dideoxy-1,2:3,4-di-O-isopropylidene-α-D-glycero-D-galacto-hept-7-enopyranose is of interest in the field of organic chemistry, particularly in the synthesis of complex carbohydrates and natural products, due to its unique structure and potential applications in drug development and chemical research.

4640-86-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4640-86-2 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, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4640-86:
(6*4)+(5*6)+(4*4)+(3*0)+(2*8)+(1*6)=92
92 % 10 = 2
So 4640-86-2 is a valid CAS Registry Number.
