Check Digit Verification of cas no
The CAS Registry Mumber 117820-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117820-80:
(8*1)+(7*1)+(6*7)+(5*8)+(4*2)+(3*0)+(2*8)+(1*0)=121
121 % 10 = 1
So 117820-80-1 is a valid CAS Registry Number.

4-Fluorobenzaldehyde was easily synthesized from 4-chlorobenzaldehyde by potassium fluoride in the presence of tetraphenylphosphonium halide plus 18-crown-6 or poly(ethylene glycol) dimethyl ether.Several fluorobenzaldehyde derivatives were similarly prepared from the corresponding chloro-derivatives in good yields.
