Check Digit Verification of cas no

The CAS Registry Mumber 82943-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82943-72:
(7*8)+(6*2)+(5*9)+(4*4)+(3*3)+(2*7)+(1*2)=154
154 % 10 = 4

Un nouveau mode de cyclisation de ceto-ylures: synthese de -furannones-3 fonctionelles

Babin, Pierre,Dunogues, Jacques,Duboudin, Francoise,Petraud, Michel

, p. 125 - 128 (2007/10/02)

Condensation of Ph3P=CH-COOEt on esters of the lactic acid chloride ClCOCH(Me)COOR' leads, according to a new cyclization process, to functional 3-furanones which undergo slow oxidation in the presence of air, giving the corresponding hydroxyfuranones.One of the latter has been chosen as a model for a complete 13C NMR study.
