89523-48-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89523-48-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,2 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89523-48:
(7*8)+(6*9)+(5*5)+(4*2)+(3*3)+(2*4)+(1*8)=168
168 % 10 = 8
So 89523-48-8 is a valid CAS Registry Number.

FACILE SYNTHESIS OF K-REGION ARENE OXIDES
Bladeren, P. J. van,Jerina, D. M.
, p. 4903 - 4906 (1983)
Polycyclic aromatic hydrocarbons reacts at the K-region with N-bromoacetamide in acetic acid to provide trans-bromohydrin acetates which are readly cyclized to arene oxides.The simplicity of the approach makes radioactive and optically active K-region arene oxides easily available.
