Check Digit Verification of cas no

The CAS Registry Mumber 106693-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,6,9 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 106693-63:
(8*1)+(7*0)+(6*6)+(5*6)+(4*9)+(3*3)+(2*6)+(1*3)=134
134 % 10 = 4
So 106693-63-4 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.
