Check Digit Verification of cas no

The CAS Registry Mumber 56421-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,2 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 56421-67:
(7*5)+(6*6)+(5*4)+(4*2)+(3*1)+(2*6)+(1*7)=121
121 % 10 = 1
So 56421-67-1 is a valid CAS Registry Number.

Synthesis of Decahydrocyclobuta[cd]indene Skeletons: Rhodium(III)-Catalyzed Hydroarylation and Relay Thiophene-Promoted Intramolecular [2+2] Cycloaddition

supporting information, p. 4384 - 4390 (2020/09/23)

The preparation of decahydrocyclobuta[cd]indene skeleton was accomplished through rhodium(III)-catalyzed hydroarylation and relay thiophene-promoted intramolecular [2+2] cycloaddition. This tandem reaction exhibited broad substrate scope (24 examples) and good functional group compatibility. Control experiments revealed the important role of sulfur (S) heteroatom, thus a tentative mechanism with thiophene-promoted double Michael additions was proposed to explain this formal [2+2] cycloaddition. Moreover, the resulting polycyclic products displayed potent anti-cancer activities against breast cancer cell lines MDA-MB-468. (Figure presented.).
