245672-37-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 245672-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,6,7 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 245672-37:
(8*2)+(7*4)+(6*5)+(5*6)+(4*7)+(3*2)+(2*3)+(1*7)=151
151 % 10 = 1
So 245672-37-1 is a valid CAS Registry Number.

Intramolecular conjugate addition reactions of amines and carbamates to 2,5-cyclohexadien-1-ones: Stereoselective synthesis of perhydroindoles

Bland, Douglas,Chambournier, Gilles,Dragan, Vladimir,Hart, David J.

, p. 8953 - 8966 (2007/10/03)

Intramolecular conjugate addition reactions of 4,4-disubstituted-2,5- cyclohexadien-1-ones are described within the context of possible approaches to manzamine A. Amine 4 provided tricycle 6, with improper relative stereochemistry for use in an approach to manzamine A. Carbamates 25 and 38 gave perhydroindoles 26 and 28 b under conditions of thermodynamic control, respectively, with the proper relative stereochemistry required for manzamine A. Carbamate 25 gave diastereomeric perhydroindole 27 under conditions of thermodynamic control.
