Check Digit Verification of cas no

The CAS Registry Mumber 71593-68-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,9 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71593-68:
(7*7)+(6*1)+(5*5)+(4*9)+(3*3)+(2*6)+(1*8)=145
145 % 10 = 5
So 71593-68-5 is a valid CAS Registry Number.

Inversion of the direction of stereoinduction in the coupling of chiral γ,δ-unsaturated fischer carbene complexes with o-ethynylbenzaldehyde

Ghorai, Binay K.,Menon, Suneetha,Lee Johnson, Dennis,Herndon, James W.

, p. 2121 - 2124 (2007/10/03)

(matrix presented) A variety of γ,δ-unsaturated carbene complexes that feature a stereogenic center at the β-carbon couple with 2-ethynylbenzaldehyde to afford hydrophenanthrene derivatives with a high degree of stereoinduction. The direction of stereoinduction is opposite for examples where the stereogenic center is acyclic vs examples where it is within a ring.
