83016-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83016-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,1 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83016-58:
(7*8)+(6*3)+(5*0)+(4*1)+(3*6)+(2*5)+(1*8)=114
114 % 10 = 4
So 83016-58-4 is a valid CAS Registry Number.

Synthesis and Spectroscopic Data of Chlorinated 4-Hydroxybenzaldehydes
Knuutinen, Juha S.,Kolehmainen, Erkki T.
, p. 139 - 141 (1983)
All chlorinated 4-hydroxybenzaldehydes including three hitherto unknown compounds have been synthesized from chlorinated phenols by applying the Reimer-Tiemann method. (1)H NMR, (13)C NMR, and mass-spectral data on all compounds are reported.
