Check Digit Verification of cas no

The CAS Registry Mumber 74023-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74023-09:
(7*7)+(6*4)+(5*0)+(4*2)+(3*3)+(2*0)+(1*9)=99
99 % 10 = 9
So 74023-09-9 is a valid CAS Registry Number.

Highly selective electroreductive linear dimerization of electron-deficient vinylarenes

supporting information, (2021/11/16)

A direct electroreductive dimerization of electron-deficient vinylarenes for the synthesis of 1,4-diarylbutane has been developed using a simple undivided cell with inexpensive carbon electrodes at room temperature. The control and deuterium-labeling experiments of electroreductive dimerization suggest that the hydrogen source comes from the solvent CH3CN. This protocol provides a mild and efficient route for the construction of C–C bond in moderate to good yields with high regioselectivity and broad substrate scope.
