Check Digit Verification of cas no

The CAS Registry Mumber 221876-08-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,8,7 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 221876-08:
(8*2)+(7*2)+(6*1)+(5*8)+(4*7)+(3*6)+(2*0)+(1*8)=130
130 % 10 = 0
So 221876-08-0 is a valid CAS Registry Number.

Synthesis of meta-substituted aniline derivatives by nucleophilic substitution

Belfield, Andrew J.,Brown, George R.,Foubister, Alan J.,Ratcliffe, Paul D.

, p. 13285 - 13300 (2007/10/03)

Substitution by amines of fluorobenzenes containing a meta- substituted electron withdrawing group (EWG), in DMSO at 100 °C over 60 h gave meta-substituted aniline derivatives in isolated yields of up to 98%. The scope of the reaction is explored in terms of reaction conditions and substrates. It is postulated that facile meta-substitutions are facilitated through field stabilisation of the intermediate anion by EWG substituents.
