104733-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104733-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,3 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104733-21:
(8*1)+(7*0)+(6*4)+(5*7)+(4*3)+(3*3)+(2*2)+(1*1)=93
93 % 10 = 3
So 104733-21-3 is a valid CAS Registry Number.

Copper-Catalyzed C(sp2)-H Difluoroalkylation of Aldehyde Derived Hydrazones with Diboron as Reductant
Ke, Miaolin,Song, Qiuling
, p. 3654 - 3664 (2016/05/24)
An efficient and general method for C(sp2)-H difluoroalkylation of aldehyde derived hydrazones via a CuII/B2pin2-catalyzed reaction between difluoroalkyl bromides and hydrazones was developed. In this reaction,
