Check Digit Verification of cas no
The CAS Registry Mumber 202534-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,5,3 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 202534-94:
(8*2)+(7*0)+(6*2)+(5*5)+(4*3)+(3*4)+(2*9)+(1*4)=99
99 % 10 = 9
So 202534-94-9 is a valid CAS Registry Number.

Catalytic Michael/Ring-Closure Reaction of α,β-Unsaturated Pyrazoleamides with Amidomalonates: Asymmetric Synthesis of (?)-Paroxetine

A highly enantioselective tandem Michael/ring-closure reaction of α,β-unsaturated pyrazoleamides and amidomalonates has been accomplished in the presence of a chiral N,N′-dioxide–Yb(OTf)3complex (Tf: trifluoromethanesulfonyl) to give various substituted chiral glutarimides with high yields and diastereo- and enantioselectivities. Moreover, this methodology could be used for gram-scale manipulation and was successfully applied to the synthesis of (?)-paroxetine. Further nonlinear and HRMS studies revealed that the real catalytically active species was a monomeric L-PMe2–Yb3+complex. A plausible transition state was proposed to explain the origin of the asymmetric induction.
