Methanol, also known as methyl alcohol or wood alcohol, is a colorless, volatile, and highly flammable liquid with the chemical formula CH3OH. It is a simple alcohol and the simplest of all alcohols, containing one carbon atom. Methanol is widely used as a solvent, antifreeze, fuel, and as a raw material in the production of other chemicals. On the other hand, (butylphosphinidene)bis- is a chemical compound with the formula C8H18P2, consisting of two butyl groups connected by a phosphorus atom. Methanol, (butylphosphinidene)bis- is less common and has limited applications compared to methanol. In summary, methanol is a widely used and versatile alcohol, while (butylphosphinidene)bis- is a less common phosphorus-containing compound with limited applications.
The CAS Registry Mumber 4762-84-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 2 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4762-84: (6*4)+(5*7)+(4*6)+(3*2)+(2*8)+(1*4)=109 109 % 10 = 9 So 4762-84-9 is a valid CAS Registry Number.
