Check Digit Verification of cas no

The CAS Registry Mumber 1374418-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,4,1 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1374418-75:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*1)+(3*8)+(2*7)+(1*5)=173
173 % 10 = 3
So 1374418-75-3 is a valid CAS Registry Number.

Dinuclear zinc catalyzed asymmetric spirannulation reaction: An umpolung strategy for formation of α-alkylated-α-hydroxyoxindoles

Trost, Barry M.,Hirano, Keiichi

, p. 2446 - 2449 (2012/07/27)

A highly diastereo- and enantioselective formal [3 + 2] cycloaddition of α,β-unsaturated esters and 3-hydroxyoxindoles catalyzed by a dinuclear zinc-ProPhenol complex is reported. The stereoselective Michael additions of 3-hydroxyoxindoles and the subsequent transesterifications afford spirocyclic δ-lactones.
