"12.15.18-Trioxo-nonacosansaeure-tris-ethylenthio-ketal" is a complex organic compound with the molecular formula C36H72O9S3. It is characterized by the presence of three ethylenethio ketal groups attached to a nonacosan-12,15,18-trione backbone. 12.15.18-Trioxo-nonacosansaeure-tris-ethylenthio-ketal is derived from a long-chain aliphatic ketone with three carbonyl groups (ketones) at the 12th, 15th, and 18th positions, which are then protected by the formation of ethylenethio ketal groups. These protective groups are formed by the reaction of the carbonyl groups with ethanedithiol, resulting in a stable, cyclic structure. The compound is of interest in organic chemistry for its unique structure and potential applications in the synthesis of other complex molecules.
The CAS Registry Mumber 4886-53-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 6 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4886-53: (6*4)+(5*8)+(4*8)+(3*6)+(2*5)+(1*3)=127 127 % 10 = 7 So 4886-53-7 is a valid CAS Registry Number.
