Check Digit Verification of cas no

The CAS Registry Mumber 864818-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,8,1 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 864818-50:
(8*8)+(7*6)+(6*4)+(5*8)+(4*1)+(3*8)+(2*5)+(1*0)=208
208 % 10 = 8
So 864818-50-8 is a valid CAS Registry Number.

Enantioselective organocatalytic intramolecular Diels-Alder reactions. The asymmetric synthesis of solanapyrone D

Wilson, Rebecca M.,Jen, Wendy S.,MacMillan, David W. C.

, p. 11616 - 11617 (2005)

The first direct enantioselective organocatalytic intramolecular Diels-Alder reaction has been accomplished. The use of iminium catalysis has provided a new catalytic strategy for the enantioselective [4 + 2] cycloisomerization of a wide variety of tethered diene-enal systems. The use of imidazolidinones 1 and 2 as the asymmetric catalysts has been found to mediate the enantioselective construction of [4.4.0] and [4.3.0] ring systems. Application of this methodology to the highly efficient asymmetric synthesis of the marine metabolite solanpyrone D has also been accomplished. A diverse spectrum of aldehyde substrates can also be accommodated in this new organocatalytic transformation. Importantly, this technology has been utilized to execute the first enantioselective, catalytic Type II IMDA reaction. Copyright
