73680-00-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73680-00-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,8 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73680-00:
(7*7)+(6*3)+(5*6)+(4*8)+(3*0)+(2*0)+(1*0)=129
129 % 10 = 9
So 73680-00-9 is a valid CAS Registry Number.

Novel N-Alkylation of Amines with Organocopper Reagents
Yamamoto, Hisashi,Maruoka, Keiji
, p. 2739 - 2740 (2007/10/02)
A mild and efficient method for the N-alkylation of amines is described, based on the oxidative coupling of lithium alkylcopper amide, which is derived from lithium dialkylcuprates and primary or secondary amines.The high chemospecificity of the method was demonstrated.
