Check Digit Verification of cas no

The CAS Registry Mumber 1428189-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,1,8 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1428189-05:
(9*1)+(8*4)+(7*2)+(6*8)+(5*1)+(4*8)+(3*9)+(2*0)+(1*5)=172
172 % 10 = 2
So 1428189-05-2 is a valid CAS Registry Number.

Gold(III)-catalyzed intramolecular furanylation and cyclopropanation of acyclic conjugated enynones

Oh, Chang Ho,Piao, Lanhua,Kim, Ji Hee

, p. 174 - 182 (2013/02/23)

We have developed an efficient cascade gold-catalyzed furanylation- cyclopropanation of acyclic (E)-deca-2,9-dien-4-yn-1-ones and an (E)-undeca-2,10-dien-4-yn-1-one to give 1-(2-furyl)bicyclo[3.1.0]hexanes and a 1-(2-furyl)bicyclo[4.1.0]heptane, respectiv
