Check Digit Verification of cas no
The CAS Registry Mumber 161759-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161759-99:
(8*1)+(7*6)+(6*1)+(5*7)+(4*5)+(3*9)+(2*9)+(1*9)=165
165 % 10 = 5
So 161759-99-5 is a valid CAS Registry Number.

Pentafluorophenyl (PFP) sulfonic esters were synthesized via a copper-catalyzed one-pot multicomponent reaction of aryl diazonium tetrafluoroborate, DABSO (DABCO·(SO2)2), and pentafluorophenol. The reaction system provided the desired pentafluorophenyl sulfonic esters in good yields and exhibited excellent functional group tolerance. In addition, the generated PFP sulfonic esters were successfully applied in Sonogashira, Suzuki, Chan-Evans-Lam, and decarboxylative coupling reactions.
