Check Digit Verification of cas no
The CAS Registry Mumber 52220-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52220-64:
(7*5)+(6*2)+(5*2)+(4*2)+(3*0)+(2*6)+(1*4)=81
81 % 10 = 1
So 52220-64-1 is a valid CAS Registry Number.

Synthesis of aryl-substituted naphthalenes by chemoselective Suzuki-Miyaura reactions of bromo-trifluoromethanesulfonyloxy-naphthalenes. Influence of steric and electronic parameters
Hassan, Zahid,Hussain, Munawar,Villinger, Alexander,Langer, Peter
experimental part, p. 6305 - 6313 (2012/08/27)
Chemoselective Suzuki-Miyaura reactions of 2-bromo-1- (trifluoromethanesulfonyloxy)naphthalene, 1-bromo-2- (trifluoromethanesulfonyloxy) naphthalene and 2-acetyl-4-bromo-1- (trifluoromethanesulfonyloxy)naphthalene, which are all readily available from the corresponding tetralone derivatives, afforded a variety of mono- and diarylnaphthalenes. The reactions generally proceed with excellent chemoselectivity in favour of the bromide position, no matter whether the bromide is located at position 1 or 2 of the naphthalene or whether the carbon attached to the triflate group is electronically more deficient by the presence of a neighbouring acetyl group.
