62404-17-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62404-17-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,0 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 62404-17:
(7*6)+(6*2)+(5*4)+(4*0)+(3*4)+(2*1)+(1*7)=95
95 % 10 = 5
So 62404-17-5 is a valid CAS Registry Number.

Palladium-catalyzed multiple arylation of thiophenes
Okazawa, Toru,Satoh, Tetsuya,Miura, Masahiro,Nomura, Masakatsu
, p. 5286 - 5287 (2002)
Secondary 2-thiophenecarboxamides efficiently undergo unique triarylation accompanied by formal decarbamoylation under palladium catalysis. 3-Substituted thiophenes, especially having an electron-withdrawing group, can also be triarylated. Copyright
