Check Digit Verification of cas no

The CAS Registry Mumber 58044-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,0,4 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 58044-82:
(7*5)+(6*8)+(5*0)+(4*4)+(3*4)+(2*8)+(1*2)=129
129 % 10 = 9
So 58044-82-9 is a valid CAS Registry Number.

Synthesis and reactivity of N-alkyl-2-oxoalkanesulfonamides

Vega, Juan A.,Alajarin, Ramon,Vaquero, Juan J.,Alvarez-Builla, Julio

, p. 3589 - 3606 (2007/10/03)

A series of N-alkyl-2-oxoalkanesulfonamides have been synthesized by reacting silyl enol ethers with N-alkyl-sulfamoyl chlorides. Their reactivity towards electrophiles was investigated in order to explore the regio- and stereoselectivity of the process. 2-Oxoalkanesulfonamides were used to prepare 5-(methylsulfamoyl)-1,4-dihydropyridines derivatives.
