Check Digit Verification of cas no

The CAS Registry Mumber 24993-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,9,9 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24993-89:
(7*2)+(6*4)+(5*9)+(4*9)+(3*3)+(2*8)+(1*9)=153
153 % 10 = 3
So 24993-89-3 is a valid CAS Registry Number.

Transition-metal-free carbonylation of aryl halides with arylboronic acids by utilizing stoichiometric CHCl3 as the carbon monoxide-precursor

Xu, Fangning,Li, Dan,Han, Wei

, p. 2911 - 2915 (2019)

Under transition-metal-free conditions, carbonylative Suzuki couplings of aryl halides with arylboronic acid using stoichiometric CHCl3 as the carbonyl source has been developed. The simple, efficient, and environmentally benign method was successfully applied to the synthesis of Fenofibric acid, naphthyl phenstatin, and carbon-13 labeled biaryl ketone.
