115909-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115909-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,0 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 115909-73:
(8*1)+(7*1)+(6*5)+(5*9)+(4*0)+(3*9)+(2*7)+(1*3)=134
134 % 10 = 4
So 115909-73-4 is a valid CAS Registry Number.

TRANSFORMATIONS OF CARBANIONIC ?-ADDUCTS OF 6-AZAQUINOXALINE DERIVATIVES
Ostrowski, Stanislaw,Makosza, Mieczyslaw
, p. 1721 - 1726 (2007/10/02)
Carbanions of α-haloalkyl aryl sulphones react with 6-azaquinoxaline via two pathways: the vicarious nucleophilic substitution of hydrogen and the bis-annulation.Factors governing these two reactions were analyzed and possibility of controlling the reacti
