Check Digit Verification of cas no
The CAS Registry Mumber 74513-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,1 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74513-16:
(7*7)+(6*4)+(5*5)+(4*1)+(3*3)+(2*1)+(1*6)=119
119 % 10 = 9
So 74513-16-9 is a valid CAS Registry Number.

Dichotomous stereocontrol in Claisen-Schmidt condensations: Synthesis of a propeller shaped rigid system
Aswathi, C. S.,Nithya, C.,Saumya, T. S.
supporting information, (2021/09/06)
Generally, Claisen-Schimdt condensation produces E-isomers of enones. However, in the Claisen Schimdt condensation between tetrahydropentalene-2,5(1H,3H)-dione and aromatic aldehydes, though initial condensations proceeded with the expected stereochemistry, subsequent condensations, where possible, produced the unexpected Z-isomers.
