Check Digit Verification of cas no

The CAS Registry Mumber 1253521-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,5,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253521-75:
(9*1)+(8*2)+(7*5)+(6*3)+(5*5)+(4*2)+(3*1)+(2*7)+(1*5)=133
133 % 10 = 3
So 1253521-75-3 is a valid CAS Registry Number.

Ytterbium triflate catalyzed synthesis of alkoxy-substituted donor-acceptor cyclobutanes and their formal [4 + 2] cycloaddition with imines: Stereoselective synthesis of piperidines

Moustafa, Mahmoud M. Abd Rabo,Pagenkopf, Brian L.

supporting information; experimental part, p. 4732 - 4735 (2010/12/25)

A new synthesis of 2-alkoxy-1,1-cyclobutane diesters and their first use in dipolar cycloadditions is reported. Both the formation of the donor-acceptor cyclobutanes and their subsequent annulation with in situ formed imines are catalyzed by Yb(OTf)3
