442-03-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 442-03-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 442-03:
(5*4)+(4*4)+(3*2)+(2*0)+(1*3)=45
45 % 10 = 5
So 442-03-5 is a valid CAS Registry Number.

CNS-agent precursor: A simple and efficient synthesis of an antipsychotic drug fluanisone
Narsaiah, A. Venkat,Nagaiah,Devi, B. Karuna
, p. 829 - 832 (2012/11/07)
An efficient synthesis of antipsychotic drug fluanisone has been carried out in seven steps with an overall yield of 32.2%. The synthesis was started from 4-fluorobenzaldehyde. All the reactions were very clean and the isolation of products was very easy.
