Check Digit Verification of cas no

The CAS Registry Mumber 1581307-32-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,3,0 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1581307-32:
(9*1)+(8*5)+(7*8)+(6*1)+(5*3)+(4*0)+(3*7)+(2*3)+(1*2)=155
155 % 10 = 5
So 1581307-32-5 is a valid CAS Registry Number.

Carbonylative suzuki couplings of aryl bromides with boronic acid derivatives under base-free conditions

Bjerglund, Klaus M.,Skrydstrup, Troels,Molander, Gary A.

, p. 1888 - 1891 (2014)

The carbonylative Suzuki-Miyaura reaction between aryl bromides and arylboronic acid equivalents is herein reported, using base-free conditions and a limited excess of carbon monoxide generated ex situ from stable CO-precursors. Under these conditions, unsymmetrical biaryl ketones were obtained in modest to excellent yields. This method was adapted to the synthesis of the triglyceride and cholesterol regulator drug, fenofibrate, and its 13C-labeled derivative in good yields from the appropriate CO-precursor.
