Check Digit Verification of cas no

The CAS Registry Mumber 688799-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,7,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 688799-55:
(8*6)+(7*8)+(6*8)+(5*7)+(4*9)+(3*9)+(2*5)+(1*5)=265
265 % 10 = 5
So 688799-55-5 is a valid CAS Registry Number.

Gold(I)-Catalyzed Conia-Ene Reaction of β-Ketoesters with Alkynes

Kennedy-Smith, Joshua J.,Staben, Steven T.,Toste, F. Dean

, p. 4526 - 4527 (2004)

The intramolecular addition of β-ketoesters to unactivated alkynes under neutral conditions and at room temperature is described. The method employs triphenylphosphinegold(I) cation as a catalyst for the formation of exo-methylenecycloalkanes. Both monocyclic and bicyclic cyclopentanes and cyclohexanes can be formed in excellent yields and with good diastereoselectivity. Copyright
