Check Digit Verification of cas no

The CAS Registry Mumber 23068-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,6 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23068-89:
(7*2)+(6*3)+(5*0)+(4*6)+(3*8)+(2*8)+(1*9)=105
105 % 10 = 5
So 23068-89-5 is a valid CAS Registry Number.

Domino imine condensation/intramolecular polar [4π+ + 2π]-cycloaddition of anilines and ω-unsaturated aldehydes: A versatile tool for the highly diastereoselective synthesis of 1,2,3,4,4a,9,9a,10-octahydroacridines

Beifuss, Uwe,Gehm, Henning,Herde, Andreas,Ledderhose, Sabine

, p. 468 - 478 (1996)

The highly diastereoselective synthesis of substituted 1,2,3,4,4a,9,9a,10-octahydroacridines 7, 8 with five stereogenic centers has been achieved by domino imine condensation/intramolecular polar [4π+ + 2π]-cycloaddition of anilines 3 and ω-uns
