Check Digit Verification of cas no
The CAS Registry Mumber 500536-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,5,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 500536-40:
(8*5)+(7*0)+(6*0)+(5*5)+(4*3)+(3*6)+(2*4)+(1*0)=103
103 % 10 = 3
So 500536-40-3 is a valid CAS Registry Number.

Selective halogen-lithium exchange of 1,2-dihaloarenes for successive [2+4] cycloadditions of arynes and isobenzofurans
Eda, Shohei,Hamura, Toshiyuki
supporting information, p. 19449 - 19462 (2015/12/31)
Successive [2+4] cycloadditions of arynes and isobenzofurans by site-selective halogen-lithium exchange of 1,2-dihaloarenes were developed, allowing the rapid construction of polycyclic compounds which serve as a useful synthetic intermediates for the preparation of various polyacene derivatives.
