Check Digit Verification of cas no
The CAS Registry Mumber 85769-75-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,6 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 85769-75:
(7*8)+(6*5)+(5*7)+(4*6)+(3*9)+(2*7)+(1*5)=191
191 % 10 = 1
So 85769-75-1 is a valid CAS Registry Number.

Catalytic Asymmetric Vinylogous Prins Cyclization: A Highly Diastereo- and Enantioselective Entry to Tetrahydrofurans

We describe the design and development of the first catalytic asymmetric vinylogous Prins cyclization. This reaction constitutes an efficient approach for highly diastereo- and enantioselective synthesis of tetrahydrofurans (THFs) and is catalyzed by a confined chiral imidodiphosphoric acid (IDP). Aromatic and heteroaromatic aldehydes react with various 3,5-dien-1-ols to afford 2,3-disubstituted THFs in excellent selectivity (d.r. > 20:1, e.r. up to 99:1). Aliphatic aldehydes react with similarly excellent results when a highly acidic imidodiphosphorimidate (IDPi) catalyst is used. With a racemic dienyl alcohol, the reaction proceeds via a kinetic resolution. DFT calculations suggest an explanation for unusually high stereoselectivity.
