1000389-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1000389-71-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,3,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1000389-71:
(9*1)+(8*0)+(7*0)+(6*0)+(5*3)+(4*8)+(3*9)+(2*7)+(1*1)=98
98 % 10 = 8
So 1000389-71-8 is a valid CAS Registry Number.

A practical synthesis of tris(pyrazolyl)methylaryls
Liddle, Brendan J.,Gardinier, James R.
, p. 9794 - 9797 (2007)
(Figure Presented) The preparation of three tris(pyrazolyl)toluidines from trifluoromethylaniline reagents is described that likely takes advantage of (quinoidal) resonance-stabilized activation of the C-F bonds. Subsequent transformations lead to two add
