1,6,11-Trimethyltriphenylene is an organic compound with the molecular formula C21H18. It is a derivative of triphenylene, a polycyclic aromatic hydrocarbon consisting of three fused benzene rings. The presence of three methyl groups (CH3) at the 1, 6, and 11 positions on the triphenylene core gives 1,6,11-trimethyltriphenylene its unique structure and properties. This chemical is known for its potential applications in the synthesis of various organic compounds and materials, such as polymers and dyes, due to its stable and conjugated system. However, it is important to note that, like other polycyclic aromatic hydrocarbons, 1,6,11-trimethyltriphenylene may have potential health and environmental concerns due to its potential carcinogenic properties.
The CAS Registry Mumber 1156-61-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 6 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1156-61: (6*1)+(5*1)+(4*5)+(3*6)+(2*6)+(1*1)=62 62 % 10 = 2 So 1156-61-2 is a valid CAS Registry Number.
