117635-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117635-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,3 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117635-50:
(8*1)+(7*1)+(6*7)+(5*6)+(4*3)+(3*5)+(2*5)+(1*0)=124
124 % 10 = 4
So 117635-50-4 is a valid CAS Registry Number.

Novel Synyhesis of Unsymmetrical Diarylbutadiynes
Nye, Susan Adams,Potts, Kevin T.
, p. 375 - 377 (2007/10/02)
Terminal arylbutadiynes, derived from 6-aryl-3,5-hexadin-2-ols, undergo a ready palladium-catalyzed coupling with activated aryl halides in the presence of a phase transfer catalyst to unsymmetrical diarylbutadiynes, not easily available by other coupling
