Check Digit Verification of cas no

The CAS Registry Mumber 125889-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,8,8 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125889-29:
(8*1)+(7*2)+(6*5)+(5*8)+(4*8)+(3*9)+(2*2)+(1*9)=164
164 % 10 = 4
So 125889-29-4 is a valid CAS Registry Number.

A NOVEL ORDER OF orto-DIRECTING ABILITIES IN THE LITHIATION OF ε6-ARENETRICARBONYLCHROMIUM(0) COMPLEXES

Gilday, John, P.,Negri, Joanna T.,Widdowson, David A.

, p. 4605 - 4618 (2007/10/02)

A ranking order of ortho-lithiation directed by various functional groups in arenetricarbonylchromium complexes has been determined.This order differs from that found in the free arene series.Inductive effects were found to be the dominant factor for the determination of the site of lithiation.Fluorine was found the most powerful ortho direction of the groups studied.Additionally, fluorine was found to be a strong ortho director in the uncomplexed series under kinetic conditions.
