3-Methoxymethyl-cyclobutan-dicarbonsaeure-(1,1)-diaethylester, also known as 3-methoxymethyl-cyclobutane-1,1-dicarboxylic acid diethyl ester, is a complex organic compound with the molecular formula C11H18O5. It features a cyclobutane ring, which is a four-carbon cyclic structure, with two ester groups attached to the 1 and 1 positions of the ring. Each ester group is derived from diethyl carbonate, which means there are two ethyl groups (C2H5) attached to the oxygen atoms of the ester. Additionally, a methoxymethyl group (-OCH2CH3) is attached to the 3 position of the cyclobutane ring. 3-Methoxymethyl-cyclobutan-dicarbonsaeure-(1,1)-diaethylester is characterized by its unique structure and potential applications in the synthesis of various pharmaceuticals and chemical intermediates.
The CAS Registry Mumber 5164-22-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 4 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5164-22: (6*5)+(5*1)+(4*6)+(3*4)+(2*2)+(1*2)=77 77 % 10 = 7 So 5164-22-7 is a valid CAS Registry Number.
