Check Digit Verification of cas no

The CAS Registry Mumber 1581731-12-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,7,3 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1581731-12:
(9*1)+(8*5)+(7*8)+(6*1)+(5*7)+(4*3)+(3*1)+(2*1)+(1*2)=165
165 % 10 = 5
So 1581731-12-5 is a valid CAS Registry Number.

Synthesis of thiazolines by copper catalyzed aminobromination of thiohydroximic acids

Lemercier, Berenice C.,Pierce, Joshua G.

supporting information, p. 2074 - 2076 (2014/05/06)

A copper catalyzed aminobromination of alkene tethered thiohydroximic acids is described, providing a rapid approach to unnatural thiazoline scaffolds not readily available via existing methods. Moderate to high yields of bromothiazolines are obtained with alkyl- and aryl-substituted thiohydroximic acid building blocks containing mono-, di-, and trisubstituted alkenes. The reaction provides high levels of 5-exo selectivity, and terminally monosubstituted alkenes result in predominant syn-diastereoselectivity.
