Check Digit Verification of cas no

The CAS Registry Mumber 1357912-51-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,9,1 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1357912-51:
(9*1)+(8*3)+(7*5)+(6*7)+(5*9)+(4*1)+(3*2)+(2*5)+(1*1)=176
176 % 10 = 6
So 1357912-51-6 is a valid CAS Registry Number.

Enantioselective one-pot synthesis of β-sulfonyl ketones and trisubstituted tetrahydrothiophenes via β-elimination/cycloaddition sequence

Xue, Lu,Liu, Yidong,Qin, Wenling,Yan, Hailong

, p. 1215 - 1218 (2018/02/09)

A mild and efficient enantioselective one-pot synthesis of β-sulfonyl ketones and trisubstituted tetrahydrothiophenes via introducing 1,4-dithiane-2,5-diol to the simple kinetic resolution of β-sulfonyl ketones has been described herein. The one-pot reaction sequence including kinetic resolution and cascade sulfa-Michael/Aldol reaction proceeded successively to afford corresponding sulfonyl ketones and tetrahydrothiophenes with high enantioselectivities (85%–98% ee and 84%–95% ee).

Hydrogen-bond-mediated cascade reaction involving chalcones: Facile synthesis of enantioenriched trisubstituted tetrahydrothiophenes

Ling, Jun-Bing,Su, Yu,Zhu, Hai-Liang,Wang, Guan-Yu,Xu, Peng-Fei

supporting information; experimental part, p. 1090 - 1093 (2012/04/04)

A bifunctional squaramide catalyzed sulfa-Michael/aldol cascade reaction between 1,4-dithiane-2,5-diol and chalcones with a low catalyst loading has been developed. Trisubstituted tetrahydrothiophenes with three contiguous stereogenic centers are obtained
