Check Digit Verification of cas no

The CAS Registry Mumber 193223-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,2,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 193223-81:
(8*1)+(7*9)+(6*3)+(5*2)+(4*2)+(3*3)+(2*8)+(1*1)=133
133 % 10 = 3
So 193223-81-3 is a valid CAS Registry Number.

A concise cross-metathesis route to enantiopure 1-azaspirocycle S

Wang, Zhen James,Spiccia, Nicolas Daniel,Gartshore, Christopher James,Illesinghe, Jayamini,Jackson, William Roy,Robinson, Andrea Jane

, p. 3118 - 3124 (2013/12/04)

A concise synthesis of spiropyrrolidines and spiropiperidines has been developed. The approach employs a ruthenium-alkylidene-catalysed cross-metathesis reaction of enantiopure N-protected allylglycine with methylenecycloalkanes. The resultant alkene intermediates can then undergo a tandem acid-catalysed cyclisation to form spiropyrrolidines. Ring expansion of the spiropyrrolidine system, via an aziridinium intermediate, grants access to the homologous spiropiperidine ring system with excellent stereoretention.
