Check Digit Verification of cas no

The CAS Registry Mumber 108191-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,9 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 108191-21:
(8*1)+(7*0)+(6*8)+(5*1)+(4*9)+(3*1)+(2*2)+(1*1)=105
105 % 10 = 5
So 108191-21-5 is a valid CAS Registry Number.

Synthesis and Anticonvulsant Activity of Analogues of 4-Amino-N-(1-phenylethyl)benzamide

Clark, C. Randall,Davenport, Timothy W.

, p. 1214 - 1218 (1987)

A group of amides and amines related to 4-amino-N-(1-phenylethyl)benzamide, 1, were prepared in a study on the relationship of structure to anticonvulsant activity in this compound. Acylation and alkylation of the amino group of 1 resulted in almost total loss of anticonvulsant activity. Insertion of a methylene between the 4-amino group and the aromatic ring of 1 produced a slight increase in anticonvulsant potency and a significant increase in toxicity. Hydride reduction of the amide carbonyl in 1 also yielded compounds having a slightly lower ED50 against convulsions induced by electroshock and a much lower TD50 in the rotorod assay. Modification of the 1-phenylethyl group of 1 also decreased anticonvulsant potency.
