Check Digit Verification of cas no
The CAS Registry Mumber 166818-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,8,1 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 166818-71:
(8*1)+(7*6)+(6*6)+(5*8)+(4*1)+(3*8)+(2*7)+(1*1)=169
169 % 10 = 9
So 166818-71-9 is a valid CAS Registry Number.

Synthesis of 5- and 6-membered heterocycles by a strategy combining SNAr and SRN1 reactions
Beugelmans, Rene,Chbani, Mohamed
, p. 306 - 313 (2007/10/02)
The SRN1 mechanism is compatible with many substituents on the benzenic substrate and allows SRN1 reactions to be combined with SNAr reactions in a strategy which brings together their corresponding synthetic advantages.Thus, compounds containing benzene fused to 5- or 6-membered heterocycles containing N (indoles), N and P (benzazaphospholes) and N and S (benzothiazines) are readily obtained. nucleophilic aromatic substitution / SRN1 / SNAr / benzene-fused heterocycles
