1248231-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1248231-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,2,3 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1248231-90:
(9*1)+(8*2)+(7*4)+(6*8)+(5*2)+(4*3)+(3*1)+(2*9)+(1*0)=144
144 % 10 = 4
So 1248231-90-4 is a valid CAS Registry Number.

CuI/DMPAO-catalyzed N-arylation of acyclic secondary amines
Zhang, Yu,Yang, Xinye,Yao, Qizheng,Ma, Dawei
, p. 3056 - 3059 (2012)
DMPAO has been found to be a powerful ligand to enable copper-catalyzed coupling of aryl halides with aliphatic acyclic secondary amines take place under relatively mild conditions, and coupling of aryl halides with primary amines and cyclic secondary amines proceeds at low catalyst loading.
