633317-93-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 633317-93-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,3,3,1 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 633317-93:
(8*6)+(7*3)+(6*3)+(5*3)+(4*1)+(3*7)+(2*9)+(1*3)=148
148 % 10 = 8
So 633317-93-8 is a valid CAS Registry Number.

Copper-catalyzed cross-coupling of aryl iodides and aryl acetylenes using microwave heating
He, Huan,Wu, Yong-Jin
, p. 3237 - 3239 (2007/10/03)
An efficient copper-catalyzed cross-coupling of aryl iodides with aryl acetylenes under microwave irradiation is described. The reaction proceeds under microwave heating with 10mol% CuI and 2equiv Cs2CO3 in 43-87% yields.
