Check Digit Verification of cas no

The CAS Registry Mumber 40891-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,9 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40891-23:
(7*4)+(6*0)+(5*8)+(4*9)+(3*1)+(2*2)+(1*3)=114
114 % 10 = 4
So 40891-23-4 is a valid CAS Registry Number.

Removal of Toluene-p-sulphonyl Groups from Sulphonamides. Part 4. Synthesis of Phenylglyoxal Imine Monomers

McKay, William R.,Proctor, George R.

, p. 2435 - 2442 (2007/10/02)

Syntheses and reactions of N-tosylphenacylamines with bases have been systematically examined.Monomeric C-methoxy-imines are available from some of these reactions.C-Methoxyphenacylarylamines, made by two routes, were converted into monomeric imines on treatment with noble-metal catalysts, The boron trifluoride-catalysed reactions of aryl aldehydes with sulphonamides provide a new and convenient route to N-sulphonylarylimines.
