Check Digit Verification of cas no
The CAS Registry Mumber 42381-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,8 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 42381-27:
(7*4)+(6*2)+(5*3)+(4*8)+(3*1)+(2*2)+(1*7)=101
101 % 10 = 1
So 42381-27-1 is a valid CAS Registry Number.

Synthesis of n-methyl benzenemethane sulfonamide substituted carbazoles and pyrazoles
Rao, B. Venugopala,Hariharakrishnan,Dubey
scheme or table, p. 1191 - 1194 (2012/08/07)
Cyclization of 1-(4-hydrazinophenyl)-N-methylmethanesulfonamide hydrochloride (2) with cyclohexanone (3)/N-methyl-4-piperidone (5) afforded the corresponding N-methyl-1-(2,3,4,9-tetrahydro-1H-carbazol-6-yl)methanesulfonamide (4) and N-methyl-1-(2-methyl- 2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-8-yl) methane sulfonamide (6). Condensation of compound 2 with substituted aryl β-diketones gave the novel N-methyl-1-[4-(3-methyl-5-phenyl-1H-pyrazol-1- yl)phenyl]methanesulfonamide (8). All the synthesized compounds were characterized by their FT-IR, 1H NMR and mass spectral data.
