(1R,2S)-1,2-Diacetylcyclopropane is a chiral organic compound with the molecular formula C7H10O2. It consists of a cyclopropane ring, which is a three-carbon ring, with two acetyl groups (CH3CO-) attached to the first and second carbon atoms in a specific configuration: R (rectus) at the first carbon and S (sinister) at the second carbon. (1R,2S)-1,2-Diacetylcyclopropane is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique strained ring structure and reactive acetyl groups. It can be synthesized through various methods, such as the reaction of cyclopropanol with acetyl chloride or through the cyclopropanation of alkenes with diketene. The compound's properties, such as its reactivity and stereochemistry, make it a valuable building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 18289-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18289-17:
(7*1)+(6*8)+(5*2)+(4*8)+(3*9)+(2*1)+(1*7)=133
133 % 10 = 3
So 18289-17-3 is a valid CAS Registry Number.
