Check Digit Verification of cas no

The CAS Registry Mumber 34034-25-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,3 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 34034-25:
(7*3)+(6*4)+(5*0)+(4*3)+(3*4)+(2*2)+(1*5)=78
78 % 10 = 8
So 34034-25-8 is a valid CAS Registry Number.

, p. 3663 - 3668 (2021)

An efficient visible-light-assisted, copper-catalyzed sulfonylation of aryl halides with sulfinates is reported. In our protocol, a single ligand CuI photocatalyst formed in situ was used in the photocatalytic transformation. Diverse organosulfones were obtained in moderate to good yields. This strategy demonstrates a promising approach toward the synthesis of diverse and useful organosulfones.
