118807-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118807-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,0 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118807-59:
(8*1)+(7*1)+(6*8)+(5*8)+(4*0)+(3*7)+(2*5)+(1*9)=143
143 % 10 = 3
So 118807-59-3 is a valid CAS Registry Number.

Coupling of 6- and 2-halo-9-phenyl-9H-purines (1, 2, and 5) with terminal acetylenes in dimethylformamide (DMF) was well catalyzed by bis(triphenylphosphino)palladium chloride to give the corresponding alkynyl-9-phenyl-9H-purines (3 and 4).
