Check Digit Verification of cas no
The CAS Registry Mumber 1217501-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,5,0 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1217501-18:
(9*1)+(8*2)+(7*1)+(6*7)+(5*5)+(4*0)+(3*1)+(2*1)+(1*8)=112
112 % 10 = 2
So 1217501-18-2 is a valid CAS Registry Number.

Cyclic Diaryl λ3-Bromanes as Original Aryne Precursors
Dherbassy, Quentin,Lanzi, Matteo,Wencel-Delord, Joanna
, p. 14852 - 14857 (2021)
Despite the widespread application of hypervalent iodines, the corresponding λ3-bromanes are less explored. Herein we report a general, safe, and high-yielding strategy to access cyclic diaryl λ3-bromanes. These unique compounds feature reactivity that is appealing and complementary to that of λ3-iodanes, generating arynes under mild reaction conditions and in the presence of a weak base. Accordingly, formal meta-selective transition-metal-free C–O and C–N couplings may be achieved. Mechanistic studies unambiguously support the aryne generation mechanism.
