Check Digit Verification of cas no

The CAS Registry Mumber 132490-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,9 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132490-23:
(8*1)+(7*3)+(6*2)+(5*4)+(4*9)+(3*0)+(2*2)+(1*3)=104
104 % 10 = 4
So 132490-23-4 is a valid CAS Registry Number.

Novel highly functionalized benzoylaminocarbothioyl pyrrolidine from benzoylisothiocyanate and substitueted pyrrolidine derived from α-aminoasit ester via imine -azomethine ylide-1,3-dipolar cycloaddition cascade

Dondas, H. Ali,Altinbas, Ozgul

, p. 167 - 173 (2004)

A series of novel highly functionalized benzoylaminocarbothioyl pyrrolidines were prepared by the reaction of benzoylisothiocyanate with substitueted pyrrolidine derived from α -aminoasit ester via metal catalsed imine -azomethine ylides-1,3-Dipolar Cycloaddition in excellent yield. An example of chiral version benzoylaminocarbothioyl pyrrolidine were also reported. The chirality oryginated from menthyl acrylate as chiral dipolarophile in the cycloaddition cascade and induced three novell chiral centres.

X=Y-ZH compounds as potential 1,3-dipoles. Part 43. Metal ion catalysed asymmetric 1,3-dipolar cycloaddition reactions of imines and menthyl acrylate

Barr, Darrin A.,Dorrity, Michael J.,Grigg, Ronald,Hargreaves, Simon,Malone, John F.,Montgomery, John,Redpath, James,Stevenson, Paul,Thornton-Pett, Mark

, p. 273 - 294 (2007/10/02)

Metallo-azomethine ylides, generated from imines by the action of amine bases in combination with LiBr or AgOAc, undergo cycloaddition with both 1R, 2S, 5R- and 1S, 2R, 5S-menthyl acrylates at room temperature to give homochiral pyrrolidines in excellent
