Check Digit Verification of cas no

The CAS Registry Mumber 1397692-29-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,6,9 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1397692-29:
(9*1)+(8*3)+(7*9)+(6*7)+(5*6)+(4*9)+(3*2)+(2*2)+(1*9)=223
223 % 10 = 3
So 1397692-29-3 is a valid CAS Registry Number.

Asymmetric construction of spirocyclohexanonerhodanines catalyzed by simple diamine derived from chiral tert-leucine

Wu, Wenbin,Huang, Huicai,Yuan, Xiaoqian,Zhu, Kailong,Ye, Jinxing

supporting information; experimental part, p. 9180 - 9182 (2012/09/22)

A diamine-catalyzed asymmetric tandem reaction between α,β- unsaturated ketones and rhodanine derivatives has been developed to synthesize various spirocyclic compounds with high stereoselectivities (up to 99% ee and >20:1 dr). The products obtained contain two pharmaceutically relevant features: the biologically active rhodanine moiety embedded in a spirocyclic unit.
