Check Digit Verification of cas no

The CAS Registry Mumber 23152-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,5 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23152-51:
(7*2)+(6*3)+(5*1)+(4*5)+(3*2)+(2*5)+(1*1)=74
74 % 10 = 4
So 23152-51-4 is a valid CAS Registry Number.

Anticonvulsant 4-Aryl Semicarbazides and Thioureas

Nagarajan, K.,David, J.,Rajappa, S.,Talwalker, S.

, p. 934 - 939 (2007/10/02)

Among a series of anticonvulsant 1-aryl semicarbazides, 1-(3,5-bistrifluoromethyl)phenylsemicarbazide, C 3884-Go (11) and its 4-methyl derivative, C 3165-Go (12) showed good activity of long duration in the electroshock test in mice and rats.Quantitative structure activity analysis indicates that ? and ? values are respectively important for the aromatic and side chain substituents respectively.N-Acetyl-N'-(3,5-bistrifluoromethyl)phenyl hydrazine (20) is highly anticonvulsant but causes ataxia. 4-Aryl thiosemicarbazides show weak to moderate activity.Among N-(3,5-bistrifluoromethyl)phenyl thiocarbamoyl derivatives, the product 33 from N-benzyl piperazine is potent in the electroshock test.Compounds 11 and 12 have been compared with standards such as phenytoin, phenurone and carbamazepine.
