1604842-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1604842-42-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,4,8,4 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1604842-42:
(9*1)+(8*6)+(7*0)+(6*4)+(5*8)+(4*4)+(3*2)+(2*4)+(1*2)=153
153 % 10 = 3
So 1604842-42-3 is a valid CAS Registry Number.

Copper-promoted oxidative coupling of enamides and alkynes for the synthesis of substituted pyrroles
Zhao, Mi-Na,Ren, Zhi-Hui,Wang, Yao-Yu,Guan, Zheng-Hui
, p. 1839 - 1842 (2014/03/21)
An efficient copper-promoted oxidative coupling of enamides with alkynes has been developed for the synthesis of substituted pyrroles. The reaction proceeded through C-H and N-H bond functionalization of enamides under mild conditions.
