Check Digit Verification of cas no

The CAS Registry Mumber 1258458-37-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,4,5 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1258458-37:
(9*1)+(8*2)+(7*5)+(6*8)+(5*4)+(4*5)+(3*8)+(2*3)+(1*7)=185
185 % 10 = 5
So 1258458-37-5 is a valid CAS Registry Number.

A general and convenient palladium-catalyzed carbonylative sonogashira coupling of aryl bromides

Wu, Xiao-Feng,Neumann, Helfried,Beller, Matthias

, p. 12104 - 12107 (2010)

Convenient carbonylations: An efficient methodology for the carbonylative Sonogashira reaction of aryl bromides has been developed (see scheme). Contrary to known procedures, inexpensive aryl bromides can be applied as substrates to give the desired compounds in moderate to good yields (47-88%).
