Check Digit Verification of cas no

The CAS Registry Mumber 162104-35-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,1,0 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 162104-35:
(8*1)+(7*6)+(6*2)+(5*1)+(4*0)+(3*4)+(2*3)+(1*5)=90
90 % 10 = 0
So 162104-35-0 is a valid CAS Registry Number.

Alkaline Hydrolysis and Alcoholysis of N-(Arylsulfonylamino)- and N-(N-Acetylarylsulfonylamino)succin- and -glutarimides

Shemchuk,Chernykh,Gritsenko,Goryachii,Ivanova

, p. 390 - 393 (2007/10/03)

Alkaline hydrolysis and alcoholysis of N-(arylsulfonylamino)- and N-(N-acetylarylsulfonylamino)-succin- and glutarimides have been studied. The reaction outcome is determined both by the size of the imide ring and by the substituent on the imide nitrogen atom. Alkaline hydrolysis of N-(N-acetylarylsulfonylamino)-succin- and -glutarimides is characterized by different order of elimination of the acetyl group and opening of the imide ring. Heating of N-(arylsulfonylamino)glutarimides in methanol in the presence of sodium methoxide results in formation of methyl 5-(arylsulfonylhydrazino)-5-oxopentanoates, whereas the reaction with N-(arylsulfonylamino)succinimides stops at the stage of formation of the corresponding sodium salt.
