Check Digit Verification of cas no

The CAS Registry Mumber 82826-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,2 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82826-29:
(7*8)+(6*2)+(5*8)+(4*2)+(3*6)+(2*2)+(1*9)=147
147 % 10 = 7
So 82826-29-7 is a valid CAS Registry Number.

THERMOLYSE COMPAREE D'ENAMINOESTERS CYCLIQUES A CINQ ET SIX CHAINONS : SYNTHESE DE TETRAHYDROINDOLES ET D'OXAZOLES

Grosdemange-Pale, Catherine,Chuche, Josselin

, p. 6183 - 6184 (2007/10/02)

The thermal behaviour of cyclic enaminoesters 1a-d shows a divergence of chemioselectivity as a function of ring size : six and five ring derivatives lead respectively to tetrahydroindoles (3a,b and 4a,b) and oxazole (5c,d).These results may be rationalized by geometrical constraints during the electrocyclisation of intermediate azomethine ylides 5.
