Check Digit Verification of cas no

The CAS Registry Mumber 166943-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,9,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 166943-01:
(8*1)+(7*6)+(6*6)+(5*9)+(4*4)+(3*3)+(2*0)+(1*1)=157
157 % 10 = 7
So 166943-01-7 is a valid CAS Registry Number.

Synthesis, properties, and reactivity of the stilbene complex of ytterbium (PhCH=CHPh)Yb(THF)2. Crystal structure of (2,4,6-But3C6H2O) 2Yb(THF)3

Trifonov,Kirillov,Fedorova,Makarenko,Bochkarev,Schumann,Muehle

, p. 2274 - 2279 (2007/10/03)

The stilbene complex of ytterbium (PhCH=CHPh)Yb(THF)2 (1) was prepared by the reaction of YbI2(THF)2 with a twofold excess of (PhCH=CHPh)-+ Li+. Based on the data of IR and ESR spectroscopy and on the results of magnetic measurements, compound 1 was characterized as a complex of divalent ytterbium with the stilbene dianion. The reactivity of complex 1 toward different types of reagents was studied. The structure of the product of the reaction of 1 with 2,4,6-tri(tert-butyl)phenol (2,4,6-But3C6H2O) 2Yb(THF)3 was established by X-ray diffraction analysis.
