Check Digit Verification of cas no

The CAS Registry Mumber 1434057-81-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,4,0,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1434057-81:
(9*1)+(8*4)+(7*3)+(6*4)+(5*0)+(4*5)+(3*7)+(2*8)+(1*1)=144
144 % 10 = 4
So 1434057-81-4 is a valid CAS Registry Number.

Scope and limitations of 1,3,5-hexatriene derivatives in regioselective cobalt-catalyzed reactions

Schmidt, Anastasia,Hilt, Gerhard

, p. 2708 - 2711 (2013)

Applications of 1,3,5-hexatriene derivatives in atom-economic cobalt-catalyzed transformations, such as the Diels-Alder reaction with alkynes, the 1,4-hydrovinylation reaction with terminal alkenes, and the 1,4-hydrohexatrienylation reaction, are investigated. In all cases, regioselective transformations were found to generate cyclic derivatives such as stilbenes or acyclic products with a high control of the double bond geometry in the skipped trienes derived from the 1,4-hydrovinylation process or the tetraenes generated in the so far unprecedented 1,4-hydrohexatrienylation reaction.
