1246436-66-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1246436-66-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,4,3 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1246436-66:
(9*1)+(8*2)+(7*4)+(6*6)+(5*4)+(4*3)+(3*6)+(2*6)+(1*6)=157
157 % 10 = 7
So 1246436-66-7 is a valid CAS Registry Number.

Efficient copper-catalyzed cross-coupling reaction of alkynes with aryl iodides
Lin, Che-Hung,Wang, Yu-Jen,Lee, Chin-Fa
, p. 4368 - 4371 (2010)
A copper-catalyzed cross-coupling reaction of alkynes with aryl iodides is described. The system, tolerates a broad range of functional groups and enables the use of sterically demanding substrates with only 1.0-2.5 mol-% of Cu 2O and 1.0-2.5 mol-% of xantphos as the catalyst.
