Check Digit Verification of cas no

The CAS Registry Mumber 111320-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,3,2 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 111320-47:
(8*1)+(7*1)+(6*1)+(5*3)+(4*2)+(3*0)+(2*4)+(1*7)=59
59 % 10 = 9
So 111320-47-9 is a valid CAS Registry Number.

Intramolecular Friedel-Crafts Acylation of N-Phthaloyl-Substituted Arylalanyl and Homophenylalanyl Chlorides

Effenberger, Franz,Steegmueller, Dieter,Null, Volker,Ziegler, Thomas

, p. 125 - 130 (2007/10/02)

N-Phthaloyl-protected arylalanyl and homophenylalanyl chlorides 5 are acylated intramolecularly to 2-phthalimido-1-indanones 6 and -1-tetralone (6d) with AlCl3 (two-fold molar amounts) or catalytic amounts of FeCl3.The cycloacylation to the tetralone 6d with AlCl3 or FeCl3 proceeds without racemisation in very good yields, whereas the cycloacylation to the indanone 6a with FeCl3 gives rise to racemisation.Mixed anhydrides 11 of N-phthaloyl-α-amino acids and trifluoromethanesulfonate were prepared from the N-phthaloylamino acid chlorides and silver triflate.Acylation of arenes 12 with 11a as well as cycloaddition of (S)-O-methyl-N-phthaloyltyrosine triflate can be achieved without racemisation and without a catalyst.
