1431317-92-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431317-92-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,3,1 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1431317-92:
(9*1)+(8*4)+(7*3)+(6*1)+(5*3)+(4*1)+(3*7)+(2*9)+(1*2)=128
128 % 10 = 8
So 1431317-92-8 is a valid CAS Registry Number.

Pd-catalyzed π-chelation assisted ortho-C-H activation and annulation of allylarenes with internal alkynes
Gandeepan, Parthasarathy,Cheng, Chien-Hong
, p. 2084 - 2087 (2013/06/05)
The synthesis of highly substituted naphthalenes from allylarenes and alkynes is described. This reaction proceeds via π-coordination of an allylic carbon-carbon double bond to the Pd(II) center and is followed by ortho selective C-H bond activation.
