Check Digit Verification of cas no

The CAS Registry Mumber 1045821-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,8,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1045821-71:
(9*1)+(8*0)+(7*4)+(6*5)+(5*8)+(4*2)+(3*1)+(2*7)+(1*1)=133
133 % 10 = 3
So 1045821-71-3 is a valid CAS Registry Number.

Multigram Scale Syntheses of First and Second Generation of Trifluoromethanesulfenamide Reagents

Glenadel, Quentin,Alazet, Sébastien,Baert, Fran?ois,Billard, Thierry

, p. 960 - 964 (2016)

Trifluoromethanesulfenamide reagents constitute a family of very efficient reagents to trifluoromethylthiolate various molecules. Optimized syntheses have been developed to easily obtain, in a reproducible manner, large quantities of these reagents, with good overall yields. Up to 84 g have already been obtained, at a reasonable cost.

Paragraph 0142-0144, (2017/09/26)

The invention discloses a trifluoromethylthio reagent as well as a synthetic method and application thereof and provides a compound I and a preparation method of the compound I. The preparation method comprises the step: reacting a compound 1a with trifluoromethylthio silver, so as to obtain the compound 1, wherein the reaction is as shown in the specification. The invention further provides application of the compound 1 as the trifluoromethylthio reagent. The compound 1 can react with amine compounds, thiol or phenolic compounds to generate the compound containing trifluoromethylthio. The trifluoromethylthio reagent 1 has the beneficial effects of high efficiency, conversion rate and yield, mild reaction conditions, low production cost and wide applicable range and is applicable to industrial production.

N-trifluoromethylthiosaccharin: An easily accessible, shelf-stable, broadly applicable trifluoromethylthiolating reagent

Xu, Chunfa,Ma, Bingqing,Shen, Qilong

supporting information, p. 9316 - 9320,5 (2014/10/15)

A new, electrophilic trifluoromethylthiolating reagent, N-trifluoromethylthiosaccharin, was developed and can be synthesized in two steps from saccharin within 30minutes. N-trifluoromethylthiosaccharin is a powerful trifluoromethylthiolating reagent and allows the trifluoromethylthiolation of a variety of nucleophiles such as alcohols, amines, thiols, electron-rich arenes, aldehydes, ketones, acyclic β-ketoesters, and alkynes under mild reaction conditions. 'Sacch'ed out: A new, electrophilic trifluoromethylthiolating reagent, N-trifluoromethylthiosaccharin (1) can be synthesized in two steps from saccharin within 30minutes. The reagent 1 allows the trifluoromethylthiolation of a variety of nucleophiles such as alcohols, amines, thiols, electron-rich arenes, aldehydes, ketones, acyclic β-ketoesters, and alkynes under mild reaction conditions.
