204528-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204528-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,2 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204528-05:
(8*2)+(7*0)+(6*4)+(5*5)+(4*2)+(3*8)+(2*0)+(1*5)=102
102 % 10 = 2
So 204528-05-2 is a valid CAS Registry Number.

Pentafluorophenol: A superior reagent for condensations in heterocyclic chemistry
Rajappan, Vasanthakumar P.,Hosmane, Ramachandra S.
, p. 753 - 764 (2007/10/03)
The use of pentafiuorophenol as a superior reagent for heterocyclic condensations, where other traditional condensing agents such as DCC and CDI failed, has been demonstrated.
