Check Digit Verification of cas no

The CAS Registry Mumber 217968-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,9,6 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 217968-04:
(8*2)+(7*1)+(6*7)+(5*9)+(4*6)+(3*8)+(2*0)+(1*4)=162
162 % 10 = 2
So 217968-04-2 is a valid CAS Registry Number.

Metal complexes of alkyne-bridged α-amino acids

Kayser, Bernd,Altman, Janina,Noeth, Heinrich,Knizek, Joerg,Beck, Wolfgang

, p. 1791 - 1798 (1998)

The palladium-mediated coupling of p-ethynylphenylalanine (p-epa) with different halogenated benzenes yielded alkyne-bridged α-amino acids. A series of cationic mono- to hexanuclear (Ph3P)2Pt complexes with the anions of p-ethynylphenylalanine and alkynyl- or benzene-bridged di-, tri-, tetra- and hexa-ethynyl phenylalanines as N,O-chelate ligands was prepared. N-t-Boc-p-ethynylphenylalanine methyl ester was metal-substituted to give complexes of the types Ph3PAu-C≡C-R and (Et3P)2Pt-(C≡CR)2. The benzene-bridged di-, tri-, tetra- and hexa-p-ethynylphenylalanine methyl esters form Schiff bases with ferrocene aldehyde and a tripodal ligand was obtained from. Ph2PCH2CH2CH2NH2 and the benzene-bridged triethynylphenyl-alanine. The structure of (Ph3P)2Pt[NH2C(H)-(CH2C 6H4C≡CH)CO2]+ BF4- was determined by X-ray diffraction.
