Check Digit Verification of cas no
The CAS Registry Mumber 1539285-81-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,9,2,8 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1539285-81:
(9*1)+(8*5)+(7*3)+(6*9)+(5*2)+(4*8)+(3*5)+(2*8)+(1*1)=198
198 % 10 = 8
So 1539285-81-8 is a valid CAS Registry Number.

Catalytic Enantioselective Nazarov Cyclization

A detailed account of an asymmetric Nazarov cyclization that leads to α-hydroxycyclopentenones bearing either vicinal, all-carbon quaternary centers, or vicinal quaternary and tertiary centers is given. The all-aliphatic examples represent the greatest challenge, as the dienone starting materials are not activated toward cyclization by an aryl group. The rational design and optimization of the substrates in parallel with optimization of the chiral Br?nsted acid catalyst is also described, as well as a series of diastereoselective transformations of a fully substituted cyclopentenone product.
