185038-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185038-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,0,3 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 185038-16:
(8*1)+(7*8)+(6*5)+(5*0)+(4*3)+(3*8)+(2*1)+(1*6)=138
138 % 10 = 8
So 185038-16-8 is a valid CAS Registry Number.

Iodide acceleration in the Pd-catalyzed coupling of aromatic 1,2-ditriflates with alkynes: Synthesis of enediynes
Powell, Noel A.,Rychnovsky, Scott D.
, p. 7901 - 7904 (2007/10/03)
Aryl enediyenes have been synthesized in a one-pot procedure by a Pd-catalyzed coupling of terminal alkynes and ortho-aryl ditriflates. A variety of substrates have been examined.
