Check Digit Verification of cas no

The CAS Registry Mumber 120975-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,7 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120975-55:
(8*1)+(7*2)+(6*0)+(5*9)+(4*7)+(3*5)+(2*5)+(1*5)=125
125 % 10 = 5
So 120975-55-5 is a valid CAS Registry Number.

Organocatalytic Enantioselective Michael-Aldol[3+2] Annulation for the Synthesis of Nitro-Methanobenzo[7] annulenes

Liu, Jin-Yu,Zhang, Xiao-Hai,Zhang, Yang

supporting information, p. 5008 - 5011 (2021/09/28)

We report an enantioselective Michael-Aldol[3+2] annulation between 2-alkyl-3-hydroxynaphthalene-1,4-diones and nitroalkenes using a bifunctional thiourea catalyst, and a series of nitro-methanobenzo[7]annulenes with potential biological activities were synthesized in good yields with excellent enantio- and diastereoselectivities. A gram-scale synthesis and further transformation of the product demonstrated the synthetic value of this reaction.
