Check Digit Verification of cas no

The CAS Registry Mumber 130669-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,6 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130669-87:
(8*1)+(7*3)+(6*0)+(5*6)+(4*6)+(3*9)+(2*8)+(1*7)=133
133 % 10 = 3
So 130669-87-3 is a valid CAS Registry Number.

Intra- and Intermolecular α-Sulfamidoalkylation Reactions

Lee, Chai-Ho,Kohn, Harold

, p. 6098 - 6104 (1990)

The utility of α-sulfamidoalkylation processes for the generation of sulfamides has been examined.Select aryl-substituted sulfamides were prepared and then treated with acid.Both intra- and intermolecular α-sulfamidoalkylation transformations were observed to proceed in moderate to good yields.The pathways for these reactions are discussed.The generality of these processes has been demonstrated using N,N'-di(aryl-substituted)sulfamides, and the utility of these reactions was examined for the preparation of cyclic sulfamides of novel structure.
