16817-34-8 Usage
General Description
3,5-dimethyl-1-benzofuran-2-carbaldehyde, also known as FREE, is a chemical compound with the molecular formula C11H10O2. It is a derivative of benzofuran and is commonly used in the fragrance and flavor industry. FREE has a sweet, floral, woody odor and is often used in perfumes, soaps, and other scented products. It is also used in the synthesis of pharmaceuticals and other organic compounds. FREE is a colorless to pale yellow liquid with a strong odor, and it is considered to be a skin irritant and sensitizer, so proper safety precautions should be taken when handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 16817-34-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,1 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16817-34:
(7*1)+(6*6)+(5*8)+(4*1)+(3*7)+(2*3)+(1*4)=118
118 % 10 = 8
So 16817-34-8 is a valid CAS Registry Number.

Preparation of highly functionalised benzofurans from ortho-hydroxyphenones and dichloroethylene: Applications and mechanistic investigations
Schevenels, Florian,Tinant, Bernard,Declercq, Jean-Paul,Markó, István E.

Highly functionalised benzofurans have been prepared from ortho-hydroxyphenones and 1,1-dichloroethylene. The key intermediate, a chloromethylene furan, smoothly rearranged into the corresponding benzofuran carbaldehyde under acidic conditions. Some mechanistic investigations have been performed and several biologically active benzofurans have been synthesised. Copyright
