54981-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54981-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,8 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54981-21:
(7*5)+(6*4)+(5*9)+(4*8)+(3*1)+(2*2)+(1*1)=144
144 % 10 = 4
So 54981-21-4 is a valid CAS Registry Number.

Potential psychotropic drugs. X. Synthesis of butyrophenone derivatives with a piperidino spiro tetrahydrooxazinone structure having neuroleptic activity
Bassus,Pacheco,Cier
, p. 416 - 423 (2007/10/05)
New neuroleptic butyrophenone derivations, with a piperidino spirotetrahydrooxa zinone ring have been synthetised. These compounds have a neuroleptic profile analogous to that of haloperidol but their effective doses are higher. They are also less toxic t
