Check Digit Verification of cas no

The CAS Registry Mumber 5617-47-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,1 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5617-47:
(6*5)+(5*6)+(4*1)+(3*7)+(2*4)+(1*7)=100
100 % 10 = 0
So 5617-47-0 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
