Check Digit Verification of cas no

The CAS Registry Mumber 14262-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,6 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 14262-18:
(7*1)+(6*4)+(5*2)+(4*6)+(3*2)+(2*1)+(1*8)=81
81 % 10 = 1
So 14262-18-1 is a valid CAS Registry Number.

Inverse electron demand hetero Diels-Alder reaction of N-sulphinylaniline with N-aryl-4H-5,7a-epoxyisoindolines

Prajapati, Dipak,Borthakur, Dipak R.,Lekhok, Kushal C.,Sandhu, Jagir S.

, p. 486 - 488 (2007/10/02)

N-Aryl-4H-5,7a-epoxyisoindolines (2) react with N-sulphinylaniline (3) in an inverse electron demand hetero Diels Alder fashion to provide the condensed 1,2-thiazene-S-oxides (4) in good yields.Both the expected regioisomers 4 and 5 have been separated by chromatographic technique and their structures established by microanalytical and spectral analyses.
