Check Digit Verification of cas no

The CAS Registry Mumber 106972-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,9,7 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106972-89:
(8*1)+(7*0)+(6*6)+(5*9)+(4*7)+(3*2)+(2*8)+(1*9)=148
148 % 10 = 8
So 106972-89-8 is a valid CAS Registry Number.

1,3-DIPOLAR CYCLOADDITION REACTIONS OF PYRAZOLIDINIUM YLIDES WITH VINYL SULFONES. A REGIOSELECTIVE SYNTHESIS OF BICYCLIC PYRAZOLIDINONE ANTIBACTERIAL AGENTS

Jungheim, Louis N.,Barnett, Charles J.,Gray, Joseph E.,Horcher, Linus H.,Shepherd, Timothy A.,Sigmund, Sandra K.

, p. 3119 - 3126 (2007/10/02)

The 1,3-dipolar cycloaddition reaction of pyrazolidinium ylide 1 with substituted vinyl sulfones 5 was studied.Elimination of benzenesulfinic acid from the resulting cycloadducts gave rise to bicyclic pyrazolidinones 3.The (E)-olefin isomers were found to undergo cycloaddition in a highly regioselective fashion.These pyrazolidinones 3 represent the nuclei of an exciting new class of potent antibacterial agents that mimic β-lactams.
