Benzo[2,1-b:3,4-b]difuran, also known as 2,3-dihydro-4,5-dimethyl-2,5-benzofurofuran, is a chemical compound with the molecular formula C10H10O2. It is a colorless to pale yellow crystalline solid that is insoluble in water but soluble in organic solvents. Benzo[2,1-b:3,4-b]difuran (8CI,9CI) is characterized by its unique structure, featuring a benzene ring fused to two furan rings, with two methyl groups attached to the benzene ring. It is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, as well as in the production of dyes and pigments. Due to its potential applications, benzo[2,1-b:3,4-b]difuran has been the subject of research and development in the chemical industry.

211-47-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 211-47-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 211-47:
(5*2)+(4*1)+(3*1)+(2*4)+(1*7)=32
32 % 10 = 2
So 211-47-2 is a valid CAS Registry Number.
