(1R,2S)-1-((S)-2-Ethoxycarbonyloxy-2-phenyl-acetylamino)-2-methyl-cyclopropanecarboxylic acid methyl ester is a complex organic compound with a molecular formula of C18H23NO5. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the R configuration at the first carbon and the S configuration at the second carbon. (1R,2S)-1-((S)-2-Ethoxycarbonyloxy-2-phenyl-acetylamino)-2-methyl-cyclopropanecarboxylic acid methyl ester features a cyclopropane ring, which is a three-carbon ring, and a methyl ester group, indicating the presence of an ester functional group derived from methanol. The molecule also includes an ethoxycarbonyloxy group, a phenyl-acetylamino group, and a methyl group. It is likely to be found in pharmaceutical or chemical research contexts, potentially as an intermediate in the synthesis of more complex molecules or as a compound with specific biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 98259-92-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,5 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98259-92:
(7*9)+(6*8)+(5*2)+(4*5)+(3*9)+(2*9)+(1*2)=188
188 % 10 = 8
So 98259-92-8 is a valid CAS Registry Number.
