Check Digit Verification of cas no

The CAS Registry Mumber 98068-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,6 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98068-28:
(7*9)+(6*8)+(5*0)+(4*6)+(3*8)+(2*2)+(1*8)=171
171 % 10 = 1
So 98068-28-1 is a valid CAS Registry Number.

(Acetoxymethyl)methylphenylgermane: Synthesis, Thermal Behaviour and Olfactoric Properties

Tacke, Reinhold,Wiesenberger, Frank

, p. 275 - 279 (2007/10/02)

(Acetoxymethyl)methylphenylgermane was synthesized by a five-step synthesis starting from trichloro(chloromethyl)germane PhCl2GeCH2Cl -> PhMeGe(Cl)CH2Cl -> PhMeGe(OAc)CH2OAc -> PhMeGe(H)CH2OH -> PhMeGe(H)CH2OAc >.The germane 1c and its carbon analogue PhMeC(H)CH2OAc (1a) are thermally stable (solutions in C6D6; 160 deg C, 48 h), whereas the structurally analogous silane PhMeSi(H)CH2OAc (1b) undergoes a rearrangement upon heating (formation of the silane PhMe2SiOAc; half-life in C6D6 at 135 deg C: 7,7 h).By analogy to the perfume 1a (hydratropyl acetate) and its silicon analogue 1b (sila-hydratropyl acetate), the germane 1c (germa-hydratropyl acetate) exhibits a sweet-floral odor.Despite of some differences, the olfactoric properties of the C/Si/Ge-analogues 1a/1b/1c are mainly characterized by analogies.
