189943-06-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189943-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,9,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189943-06:
(8*1)+(7*8)+(6*9)+(5*9)+(4*4)+(3*3)+(2*0)+(1*6)=194
194 % 10 = 4
So 189943-06-4 is a valid CAS Registry Number.

A short and versatile synthesis of 3-substituted 2-aminoquinolines

Compagnone, Reinaldo S.,Suarez, Alirica I.,Zambrano, Jorge L.,Pina, Ivette C.,Dominguez, Jose N.

, p. 1631 - 1641 (2007/10/03)

A short and versatile synthesis of a series of 3-substituted 2-aminoquinolines was accomplished in good yields starting from 2-nitrobenzaldehyde. Organic phosphonates were used as key synthetic intermediates and in some cases amino acids as readily available starting materials. The final two key steps of the sequence involving a reduction and ring closure that led to the 2-aminoquinoline skeleton were carried out in a 'one pot' procedure using SnCL22H2O.
