Dibenzo[b,f]thiepin is a structural class of compounds explored for their neurotropic, psychotropic, and antihistamine activities. Derivatives such as 9-chloro-10-(4-methylpiperazino)-10,11-dihydrodibenzo[b,f]thiepin have been synthesized and studied, though substitution at the 9th position was found to diminish neuroleptic activity, rendering it inactive as a central depressant or cataleptic agent. Other modifications, including alkyl and piperazino substitutions, have been investigated for their potential in treating CNS disorders, gastric conditions, and as antihistamines, highlighting the versatility of this scaffold in medicinal chemistry.

257-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 257-13-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 257-13:
(5*2)+(4*5)+(3*7)+(2*1)+(1*3)=56
56 % 10 = 6
So 257-13-6 is a valid CAS Registry Number.
