67634-08-6 Usage
General Description
Tetrahydro-alpha-pentylfurfuryl acetate, also known as Penta Furan, is a synthetic organic compound commonly used in the fragrance and flavor industry. It is a clear, colorless liquid with a sweet, floral odor and is often used as a top note in perfumes due to its pleasant, fruity aroma. It is derived from furfural, a natural organic compound found in many plants, and is commonly used in a variety of personal care and home care products. Penta Furan is known for its ability to add depth and complexity to fragrances, and is often used to impart a sweet, woody, and slightly fruity scent to perfumes and other scented products. It is considered safe for use in consumer products when used in accordance with regulations and guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 67634-08-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,3 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67634-08:
(7*6)+(6*7)+(5*6)+(4*3)+(3*4)+(2*0)+(1*8)=146
146 % 10 = 6
So 67634-08-6 is a valid CAS Registry Number.

One-pot regio- and stereoselective cyclization of 1,2,n-triols
Zheng, Tao,Narayan, Radha S.,Schomaker, Jennifer M.,Borhan, Babak
, p. 6946 - 6947 (2007/10/03)
A simple and efficient process to cyclize triols containing a 1,2-diol functionality with a pendant hydroxyl group is presented. The one-pot procedure converts the 1,2-diol into an ortho ester in situ, which upon treatment with a Lewis acid generates a cyclic acetoxonium intermediate. This intermediate is subsequently trapped by the pendant hydroxyl group to generate a cyclic ether. The stereochemistry of the 1,2-diol is transferred to the product with complete fidelity (inversion at the site of cyclization), and the reaction proceeds with high regioselectivity. The process is akin to the Lewis acid-catalyzed intramolecular ring-opening of epoxides with hydroxyl groups yielding cyclic ethers of various sizes with regio- and stereochemical control. Copyright
