Check Digit Verification of cas no

The CAS Registry Mumber 154120-68-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,2 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 154120-68:
(8*1)+(7*5)+(6*4)+(5*1)+(4*2)+(3*0)+(2*6)+(1*8)=100
100 % 10 = 0
So 154120-68-0 is a valid CAS Registry Number.

Synthese und Koordinationschemie tripodaler, aromatischer Triisocyanide

Hahn, F. Ekkehardt,Tamm, Matthias

, p. 103 - 112 (2007/10/02)

The tripodal aromatic triisocyanides HC(CH2CH2CH2O-2-C6H4NC)3 (5) and H3C-C(CH2O-2-C6H4NC)3 (6) react with (C7H8)W(CO)3 to give the chelate complexes fac- (15) und fac- (16). 15 was shown by NMR spectroscopy to be a 5:3 mixture of two isomers, in which the central methine group of the ligand adopts either the in- (15a) or the out-configuration (15b) respectively.The molecular structure of 16 in which 6 adopts the out-configuration exclusively, has been determined by X-ray structure analysis. Key words: Isocyanide; Tungsten; X-ray diffraction
