(2R,3R)-2-ethyl-3-(methoxymethoxy)-1-butanal is a chiral organic compound characterized by its specific stereochemistry, with the R configuration at both the 2nd and 3rd carbon atoms. It features a butanal backbone, which is a four-carbon aldehyde, with an ethyl group at the 2nd carbon and a methoxymethoxy group at the 3rd carbon. The methoxymethoxy group is an ether derivative, consisting of two methoxy groups (-OCH3) attached to an oxygen atom, which can be involved in various chemical reactions due to its reactivity. (2R,3R)-2-ethyl-3-(methoxymethoxy)-1-butanal is significant in organic chemistry, particularly in the synthesis of complex molecules and pharmaceuticals, where stereochemistry plays a crucial role in determining the biological activity of the final product.
The CAS Registry Mumber 87519-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,1 and 9 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 87519-18: (7*8)+(6*7)+(5*5)+(4*1)+(3*9)+(2*1)+(1*8)=164 164 % 10 = 4 So 87519-18-4 is a valid CAS Registry Number.
