Check Digit Verification of cas no
The CAS Registry Mumber 550998-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,0,9,9 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 550998-27:
(8*5)+(7*5)+(6*0)+(5*9)+(4*9)+(3*8)+(2*2)+(1*7)=191
191 % 10 = 1
So 550998-27-1 is a valid CAS Registry Number.

A Visible Light and Iron-mediated Carbocationic Route to Polysubstituted 1-Halonaphthalenes by Benzannulation using Allylbenzenes and Polyhalomethanes

A wide array of polysubstituted 1-bromo and chloronaphthalenes are obtained from coupling of allylbenzenes and polyhalomethanes. The reaction is mediated by iron metal under visible light irradiation and proceeds via a Kharasch addition intermediate followed by intramolecular FeIII mediated Friedel-Crafts alkylation, with the formation of two Csp2?Csp2 bonds in the process. This method gives easy access to 1-halonaphthalenes with substituent(s) at C-5 to C-8 that are otherwise hard to synthesize. (Figure presented.).
