67191-50-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67191-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67191-50:
(7*6)+(6*7)+(5*1)+(4*9)+(3*1)+(2*5)+(1*0)=138
138 % 10 = 8
So 67191-50-8 is a valid CAS Registry Number.

Amidation through carbamates
Latorre, Antonio,Rodríguez, Santiago,Izquierdo, Javier,González, Florenci V.
experimental part, p. 2653 - 2655 (2009/08/09)
N-Alkyl carbamates of primary amines are easily converted into amides under treatment with Grignard reagents. Consequently, primary amines can be converted into amides in a one-pot reaction through carbamate protection and Grignard addition.
