Check Digit Verification of cas no

The CAS Registry Mumber 172032-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,0,3 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172032-98:
(8*1)+(7*7)+(6*2)+(5*0)+(4*3)+(3*2)+(2*9)+(1*8)=113
113 % 10 = 3
So 172032-98-3 is a valid CAS Registry Number.

Synthesis of Carboxylated Pyrrolidine Derivatives via 1,3-Dipolar Cycloadditions of Homochiral Double-Stabilised E-Azomethine Ylids.

Harwood, L. M.,Lilley, I. A.

, p. 1557 - 1560 (1995)

The preparation and subsequent diastereoselective 1,3- dipolar cycloaddition of E-carboethoxy-substituted azomethine ylids derived by condensating 5-(S)-phenylmorpholinone (1) with ethyl glyoxalate is described.Removal of the chiral template furnishes enantiomerically pure pyrrolidine-2,5-dicarboxylate derivatives.
