59405-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59405-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,0 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 59405-47:
(7*5)+(6*9)+(5*4)+(4*0)+(3*5)+(2*4)+(1*7)=139
139 % 10 = 9
So 59405-47-9 is a valid CAS Registry Number.

Diazo-coupling reaction on ion-exchange resin support
Das, P. J.,Khound, S.,Dutta, J.
, p. 161 - 163 (2007/10/02)
Diazonium ions have been immobilized on a cation exchange resin and brought into reaction with suitable substrate to give azo compounds as the only product.Byproducts are absent and recovery of the products is simple.These diazocoupling reactions could be carried out in organic solvents and under neutral condition.
