The CAS Registry Mumber 1204394-61-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,3,9 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1204394-61:
(9*1)+(8*2)+(7*0)+(6*4)+(5*3)+(4*9)+(3*4)+(2*6)+(1*1)=125
125 % 10 = 5
So 1204394-61-5 is a valid CAS Registry Number.

Chiral Phosphine–Phosphite Ligands in Asymmetric Gold Catalysis: Highly Enantioselective Synthesis of Furo[3,4-d]-Tetrahydropyridazine Derivatives through [3+3]-Cycloaddition

Du, Qingwei,Neud?rfl, J?rg-Martin,Schmalz, Hans-Günther

, p. 2379 - 2383 (2018/01/27)

The AuI-catalyzed reaction of 2-(1-alkynyl)-2-alken-1-ones with azomethine imines regio- and diastereoselectively affords furo[3,4-d]tetrahydropyridazines in a tandem cyclization/intermolecular [3+3]-cycloaddition process under mild conditions.
