24784-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24784-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,8 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24784-69:
(7*2)+(6*4)+(5*7)+(4*8)+(3*4)+(2*6)+(1*9)=138
138 % 10 = 8
So 24784-69-8 is a valid CAS Registry Number.

Tetrabutylammonium triphenydifluorosilicate (TBAT) has been found to be a useful reagent for the conversion of 6-chloropurine nucleosides to 6- fluoropurine derivatives. The 6-chloropurine nucleosides were reacted with trimethylamine to form quaternary tr
