Check Digit Verification of cas no

The CAS Registry Mumber 160820-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,8,2 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 160820-67:
(8*1)+(7*6)+(6*0)+(5*8)+(4*2)+(3*0)+(2*6)+(1*7)=117
117 % 10 = 7
So 160820-67-7 is a valid CAS Registry Number.

Synthesis and Complex Chemistry of Functionalised Tripod Ligands RC(CH2PPh2)3

Janssen, Bernd C.,Sernau, Volker,Huttner, Gottfried,Asam, Alexander,Walter, Olaf,et al.

, p. 63 - 70 (2007/10/02)

Malonic ester 1 is alkylated and converted into the triols RC(CH2OH)3 (5).These are easily converted into the corresponding functionalised tripodal ligands RC(CH2PPh2)3 (7) with R = Bzl (a), n-C12H25 (b), (CH3)2CH(CH2)2 (c).Crystals suitable for X-ray crystallography have been obtained of the ligand 7a.In addition, the tripod ligands 7a and 7c have been further characterized by the syntheses and X-ray analyses of the nickel complex (8a), the iron complex (BF4)2 ; and the cobalt complex >(BPh4)(10*BF4). - Key Words: Tripod ligand synthesis / Tripod nickel chloro complexes / Tripod iron tris(acetonitrile) complexes / Tripod cobalt acetate complexes
