Check Digit Verification of cas no
The CAS Registry Mumber 83933-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,3 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83933-16:
(7*8)+(6*3)+(5*9)+(4*3)+(3*3)+(2*1)+(1*6)=148
148 % 10 = 8
So 83933-16-8 is a valid CAS Registry Number.

The protonation behaviour at 25 deg C in aqueous sulphuric acid solution of some 3-, 4-, and 5-substituted thiophen-2-carboxamides has been investigated by u.v. spectrophotometry. pKBH+ Values were calculated by HA and Bunnett-Olsen methods using the multivariate analysis.A positive ?α-s value was obtained indicating that the sulphur atom acts as an electron-withdrawing substituent.Plots of pKBH+of 4- and 5-substituted thiophen-2-carboxamides and 3-substituted derivatives against ? were linear with the slope +1.10 and +1.28, respectively.A ρo/ρm,p ratio higher than unity (1.16) has been observed indicating a larger transmission of electronic effects between the 2- and 3-positions of the thiophen ring than between the 2- and 4- or 5-positions.
