Check Digit Verification of cas no

The CAS Registry Mumber 1047668-36-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,7,6,6 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1047668-36:
(9*1)+(8*0)+(7*4)+(6*7)+(5*6)+(4*6)+(3*8)+(2*3)+(1*6)=169
169 % 10 = 9

O-Dihaloarenes as aryne precursors for nickel-catalyzed [2 + 2 + 2] cycloaddition with alkynes and nitriles

Hsieh, Jen-Chieh,Cheng, Chien-Hong

, p. 2992 - 2994 (2008)

o-Dihaloarenes acting as aryne precursors react with acetylenes and nitriles catalyzed by the NiBr2(dppe)/dppe/Zn system to give substituted naphthalene, phenanthridine or triphenylene derivatives depending on the reaction conditions in moderat
