69193-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69193-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,9 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 69193-55:
(7*6)+(6*9)+(5*1)+(4*9)+(3*3)+(2*5)+(1*5)=161
161 % 10 = 1
So 69193-55-1 is a valid CAS Registry Number.

β-Lactam scaffolds are considered to be ideal building blocks for the synthesis of nitrogen-containing compounds. A new palladium-catalyzed oxidative carbonylation of N-allylamines for the synthesis of α-methylene-β- lactams is reported. DFT calculations suggest that the formation of β-lactams via a four-membered-ring transition state is favorable. Four corners: The β-lactam scaffold is considered to be an ideal building block for the synthesis of nitrogen-containing compounds.
