Check Digit Verification of cas no

The CAS Registry Mumber 139026-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,2 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139026-12:
(8*1)+(7*3)+(6*9)+(5*0)+(4*2)+(3*6)+(2*1)+(1*2)=113
113 % 10 = 3
So 139026-12-3 is a valid CAS Registry Number.

Synthesis and hydride reductions of chiral cyclic β-iminosulfoxides

Carreno, M. Carmen,Dominguez, Esteban,Garcia Ruano, Jose L.,Pedregal, Concepcion,Rodriguez, Jesus H.

, p. 10035 - 10044 (1991)

The hydride reductions of chiral N-(2-p-tolylsulfmyl)cyclohexylidene phenyl amines 3A and 3B (epimers at C-2), and of N-1-(2-p-tolylsulfinyl)cyclohexenyl benzyl amine, 4, are highly stereoselective, yielding only the corresponding cis-aminosulfoxides.
