Check Digit Verification of cas no

The CAS Registry Mumber 1219804-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,8,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1219804-52:
(9*1)+(8*2)+(7*1)+(6*9)+(5*8)+(4*0)+(3*4)+(2*5)+(1*2)=150
150 % 10 = 0
So 1219804-52-0 is a valid CAS Registry Number.

Identification and Responsibility of 2,4,6-Tribromoanisole in Musty, Corked Odors in Wine

Chatonnet, Pascal,Bonnet, Sandra,Boutou, Stephane,Labadie, Marie-Dominique

, p. 1255 - 1262 (2004)

In this work, gas phase chromatography analysis coupled with selective selected ion monitoring (SIM) identified 2,4,6-tribromoanisole (TBA) in wines found on tasting to have significant musty or corked character, although they did not contain noteworthy quantities of chloroanisoles or chlorophenols, the contaminants generally reported to cause this type of defect. The perception thresholds were studied, together with contamination conditions during winemaking, storage, and bottle-aging. A musty off-odor was perceptible on smelling wine containing as little as 4 ng L-1 TBA, and spoilage may be detected by retro-olfaction at even lower concentrations. TBA, produced by O-methylation of its direct precursor, 2,4,6-tribromophenol, generally comes from sources in the winery environment. This paper is the first to identify the sources of a large number of cases of wines polluted during storage in premises where the atmosphere was contaminated with TBA used recently to treat wood, or originating from much older structural elements of the winery, or from used wooden containers. In certain cases, although the initial source had been eliminated, residual pollution adsorbed on walls could be sufficient to make a building unsuitable for storing wooden barrels and plastics, as well as corks, which have been found to be particularly susceptible to contamination by the TBA in the winery atmosphere.
