Check Digit Verification of cas no

The CAS Registry Mumber 69052-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,5 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69052-20:
(7*6)+(6*9)+(5*0)+(4*5)+(3*2)+(2*2)+(1*0)=126
126 % 10 = 6
So 69052-20-6 is a valid CAS Registry Number.

supporting information, p. 7966 - 7971 (2021/10/25)

A cascade 8πelectrocyclization/benzannulation reaction was developed to obtain the synthetically important highly substituted phenyl-pyridines. This method shows great potential in the rapid and inexpensive application of the scalable and operationally simple production of accessible substrates. On the basis of the resulting phenyl-pyridine products, a new Ru catalyst and bidentate ligand were designed and prepared, further demonstrating its high practicability.
