General Description
2,7-dimethyl-9H-fluorene is a polycyclic aromatic hydrocarbon compound with the chemical formula C15H12. It is a white to off-white crystalline solid that is insoluble in water but soluble in organic solvents. 2,7-dimethyl-9H-fluorene is commonly used as a building block in the synthesis of various organic compounds, including pharmaceuticals, dyes, and polymers. It is considered to be a hazardous chemical, as it is a suspected carcinogen and can cause irritation and damage to the respiratory system if inhaled. Additionally, 2,7-dimethyl-9H-fluorene is flammable and may release toxic fumes when heated to decomposition. Therefore, appropriate safety precautions should be taken when handling and storing this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 2851-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,5 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2851-80:
(6*2)+(5*8)+(4*5)+(3*1)+(2*8)+(1*0)=91
91 % 10 = 1
So 2851-80-1 is a valid CAS Registry Number.
