"2,2',5'-Trioxo-1',3'-di-p-tolylspiro[acenaphthen-1,4'-imidazolidin]" is a complex organic compound characterized by its unique molecular structure. It features a spiro ring system, which is a fused ring system where two rings share a common atom. In this case, the spiro system connects an acenaphthene and an imidazolidin ring. The compound is further defined by the presence of three oxygen atoms in keto form (trioxo) and two para-tolyl groups attached to the imidazolidin ring. Para-tolyl groups refer to methyl groups positioned at the para position relative to each other on a benzene ring. 2,2',5'-Trioxo-1',3'-di-p-tolylspiro is likely to be of interest in the field of organic chemistry, potentially for its specific reactivity or as a building block in the synthesis of more complex molecules.
The CAS Registry Mumber 85036-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,0,3 and 6 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 85036-91: (7*8)+(6*5)+(5*0)+(4*3)+(3*6)+(2*9)+(1*1)=135 135 % 10 = 5 So 85036-91-5 is a valid CAS Registry Number.
