138330-48-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138330-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,3 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138330-48:
(8*1)+(7*3)+(6*8)+(5*3)+(4*3)+(3*0)+(2*4)+(1*8)=120
120 % 10 = 0
So 138330-48-0 is a valid CAS Registry Number.

A new pathway to alkynyl ketones via palladium-catalyzed carbonylative coupling of vinyl triflates with 1-alkynes
Ciattini, Pier Giuseppe,Morera, Enrico,Ortar, Giorgio
, p. 6449 - 6452 (2007/10/02)
The palladium-catalyzed coupling reaction of vinyl triflates with 1-alkynes in the presence of carbon monoxide takes place under mild conditions to produce 1-alken-4-yn-3-ones in moderate to good yields.
