2-Methoxycarbonyl-4,6-dihydrothieno<3,4-b>thiophene 5,5-dioxide is a complex organic compound with the molecular formula C7H8O4S3. It is a derivative of the thieno-thiophene system, which is a fused ring structure consisting of a thiophene (a five-membered ring with one sulfur atom) and a benzene ring. The compound features a 5,5-dioxide group, indicating the presence of two oxygen atoms bonded to the same carbon atom, and a methoxycarbonyl group (-COOCH3) at the 2-position. This molecule is of interest in the field of organic chemistry, particularly in the synthesis of pharmaceuticals and other specialty chemicals, due to its unique structure and potential reactivity.
The CAS Registry Mumber 7712-06-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,1 and 2 respectively; the second part has 2 digits, 0 and 6 respectively. Calculate Digit Verification of CAS Registry Number 7712-06: (6*7)+(5*7)+(4*1)+(3*2)+(2*0)+(1*6)=93 93 % 10 = 3 So 7712-06-3 is a valid CAS Registry Number.
