Check Digit Verification of cas no
The CAS Registry Mumber 5333-90-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5333-90:
(6*5)+(5*3)+(4*3)+(3*3)+(2*9)+(1*0)=84
84 % 10 = 4
So 5333-90-4 is a valid CAS Registry Number.

Rh-Catalyzed Annulation of Benzoic Acids, Formaldehyde, and Malonates via ortho-Hydroarylation to Indanones
Yu, Shuling,Lv, Ningning,Hong, Chao,Liu, Zhanxiang,Zhang, Yuhong
supporting information, p. 8354 - 8358 (2020/11/18)
A three-component reaction from readily available low-cost materials of benzoic acids, formaldehyde, and malonates for the preparation of indanones by rhodium catalysis is reported. The annulation is initiated by an ortho-hydroarylation of benzoic acids, and a Lewis acid is not required. The solvent has a significant influence to the reaction, and 2-substituted or nonsubstituted indanones are obtained by the change of solvent.
