Check Digit Verification of cas no

The CAS Registry Mumber 1856-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1856-05:
(6*1)+(5*8)+(4*5)+(3*6)+(2*0)+(1*5)=89
89 % 10 = 9
So 1856-05-9 is a valid CAS Registry Number.

Selective silylation of alcohols, phenols and oximes using N-chlorosaccharin as an efficient catalyst under mild and solvent-free conditions

Aghapour, Ghasem,Moghaddam, Ali Kazemi,Nadali, Samaneh

, p. 197 - 203 (2015/05/12)

Efficient silylation of OH group in alcohols, phenols and oximes is described using a catalytic amount of N-chlorosaccharin and hexamethyldisilazane (HMDS) under mild and solvent-free conditions. This silylation reaction can be carried out with excellent and interesting various selectivities.

Determination of total cholesterol in serum by gas chromatography-mass spectrometry

Lian, Kaoqi,Zhang, Pingping,Wang, Wei,Dai, TIngting,Li, Lei

, p. 2646 - 2648 (2014/06/09)

In this study, a reliable protocol for determination of total cholesterol in serum using gas chromatography-mass spectrometry was established. The total free cholesterol was extracted from the serum with chloroform and derivatized with bis(trimethylsilyl)trifluoroacetamide, analyzed without the saponification step commonly used. Linear calibration curves of cholesterol were obtained from the concentration 0.1 to 15 mmol L-1. The limit of detection was 0.04 mmol L-1. Finally, the proposed method was to explore the influence of high cholesterol diet on total cholesterol in serum of rats.

Alum: An efficient catalyst for trimethylsilylation of alcohols and phenols with hexamethyldisilazane

Yang, Xiaojuan,Liang, Jinying

experimental part, p. 228 - 230 (2012/08/07)

A highly convenient method for the trimethylsilylation of alcohols and phenols via treatment by hexamethyldisilazane in the presence of alum as a catalyst has been developed. A wide variety of hydroxyl groups were selectively protected in CH3CN under mild conditions.
