1421683-75-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421683-75-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,8 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421683-75:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*8)+(3*3)+(2*7)+(1*5)=151
151 % 10 = 1
So 1421683-75-1 is a valid CAS Registry Number.

Copper-catalyzed C-H alkoxylation of azoles
Takemura, Noriaki,Kuninobu, Yoichiro,Kanai, Motomu
, p. 844 - 847 (2013/03/28)
We achieved copper-catalyzed intramolecular and intermolecular alkoxylation of azoles. This reaction is a rare example of transition-metal-catalyzed C-H alkoxylation of heteroaromatic compounds. In addition, the alkoxylation reaction proceeded well even i
