Check Digit Verification of cas no

The CAS Registry Mumber 188004-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,0,0 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 188004-30:
(8*1)+(7*8)+(6*8)+(5*0)+(4*0)+(3*4)+(2*3)+(1*0)=130
130 % 10 = 0
So 188004-30-0 is a valid CAS Registry Number.

Synthesis of 2-Alkenyl-Tethered Anilines

Denmark, Scott E.,Chi, Hyung Min

, p. 2873 - 2888 (2017)

Three general routes for the synthesis of (E)-2-alkenyl-tethered anilines have been developed. The first route involves a 3-aza-Cope rearrangement of N -allylic anilines in the presence of a Lewis acid. The requisite N -allylic anilines were prepared by t

A study on the regio- and stereoselectivity in palladium-catalyzed cyclizations of alkenes and alkynes bearing bromoaryl and nucleophilic groups

Bruyère, Didier,Bouyssi, Didier,Balme, Geneviève

, p. 4007 - 4017 (2007/10/03)

We have studied the remarkable dependence of the stereochemistry of the cyclization on the double bond geometry and of the effect of the bulkiness of the nucleophile on the regiochemistry of the palladium mediated cyclization of alkenes bearing aryl bromides and nucleophiles. In contrast, the cyclization of the acetylenic homologous substrates is not dependent on the nature of the nucleophile.
