Check Digit Verification of cas no

The CAS Registry Mumber 153729-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,2 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153729-83:
(8*1)+(7*5)+(6*3)+(5*7)+(4*2)+(3*9)+(2*8)+(1*3)=150
150 % 10 = 0
So 153729-83-0 is a valid CAS Registry Number.

supporting information, p. 5826 - 5830 (2018/09/25)

A synthetic route to chiral selenazolines from readily available N-acyloxazolidinones via a selenative rearrangement of a chiral cyclic skeleton is reported. The reaction proceeds in the presence of elemental selenium, a hydrochlorosilane, and an amine. A

Decarboxylative isomerization of N-Acyl-2-oxazolidinones to 2-oxazolines

May, Aaron E.,Willoughby, Patrick H.,Hoye, Thomas R.

, p. 3292 - 3294 (2008/09/20)

(Chemical Equation Presented) N-Acyl-2-oxazolidinones are ring-opened by lithium iodide and decarboxylated in the presence of a mild proton source. Further reaction with an amine base provides 2-oxazolines. The transformation is general for oxazolidinones unsubstituted in the 5 position and occurs under mild conditions (25-50°C). These results complement the existing methods for this transformation by allowing lower temperatures and/or avoiding metal catalysts.
