Check Digit Verification of cas no

The CAS Registry Mumber 870094-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,0,9 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 870094-80:
(8*8)+(7*7)+(6*0)+(5*0)+(4*9)+(3*4)+(2*8)+(1*0)=177
177 % 10 = 7
So 870094-80-7 is a valid CAS Registry Number.

Dynamic kinetic resolution of α,β-unsaturated lactones through asymmetric copper-catalyzed conjugate reduction: Application to the total synthesis of eupomatilone-3

Rainka, Matthew P.,Milne, Jacqueline E.,Buchwald, Stephen L.

, p. 6177 - 6180 (2005)

(Chemical Equation Presented) Only six steps were needed for the total synthesis of eupomatilone-3 in 48 % overall yield thanks to the development of a dynamic kinetic resolution that allowed the reductive conversion of a racemic α,β-unsaturated butenolid
