1171817-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1171817-73-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,8,1 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1171817-73:
(9*1)+(8*1)+(7*7)+(6*1)+(5*8)+(4*1)+(3*7)+(2*7)+(1*3)=154
154 % 10 = 4
So 1171817-73-4 is a valid CAS Registry Number.

New and efficient protocol for arylation of quinones
Demchuk, Oleg M.,Pietrusiewicz, K. Micha?
scheme or table, p. 1149 - 1153 (2009/10/17)
A practical rhodium-mediated arylation of 1,4-quinones has been developed. The corresponding 2-aryl-1,4-quinones were obtained with excellent selectivity and high yields under convenient aerobic reaction conditions. Georg Thieme Verlag Stuttgart.
