Check Digit Verification of cas no

The CAS Registry Mumber 321166-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,1,6 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 321166-01:
(8*3)+(7*2)+(6*1)+(5*1)+(4*6)+(3*6)+(2*0)+(1*1)=92
92 % 10 = 2
So 321166-01-2 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.
