Check Digit Verification of cas no

The CAS Registry Mumber 1206518-38-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,5,1 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1206518-38:
(9*1)+(8*2)+(7*0)+(6*6)+(5*5)+(4*1)+(3*8)+(2*3)+(1*8)=128
128 % 10 = 8
So 1206518-38-8 is a valid CAS Registry Number.

Rearrangement of oxazolidinethiones to thiazolidinediones or thiazinanediones and their application for the synthesis of chiral allylic ureas and α-methyl-β-amino acids

Sabala, Rocio,Hernández, Jacqueline,Carranza, Vladimir,Meza-León, Rosa L.,Bernès, Sylvain,Sansinenea, Estibaliz,Ortiz, Aurelio

scheme or table, p. 111 - 120 (2010/03/01)

A novel rearrangement has been found between oxazolidinethiones and acyl halides under N-acylation reaction conditions to afford N-substituted 2,4-thiazolidinediones and N-substituted 1,3-thiazinane-2,4-diones. These heterocycles were used for the synthesis of chiral allylic ureas and α-methyl-β-amino acids.
