Check Digit Verification of cas no

The CAS Registry Mumber 1520038-70-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,2,0,0,3 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1520038-70:
(9*1)+(8*5)+(7*2)+(6*0)+(5*0)+(4*3)+(3*8)+(2*7)+(1*0)=113
113 % 10 = 3
So 1520038-70-3 is a valid CAS Registry Number.

Iron(III) chloride catalyzed synthesis of functionalized spiropyrimidines

Majumdar,Ponra, Sudipta,Ghosh, Tapas

supporting information, p. 3164 - 3172 (2013/12/04)

Potentially bioactive pyrimidine-annulated spiroheterocyclic compounds are synthesized in good to excellent yields using readily available, cheap and environmentally friendly iron(III) chloride (FeCl3) as the catalyst. The process is straightforward and provides a diverse range of spiropyrimidine derivatives via the 5-endo-dig mode of cyclization, starting from simple and easily available starting materials.
