Check Digit Verification of cas no

The CAS Registry Mumber 1048703-33-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,8,7,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1048703-33:
(9*1)+(8*0)+(7*4)+(6*8)+(5*7)+(4*0)+(3*3)+(2*3)+(1*3)=138
138 % 10 = 8
So 1048703-33-8 is a valid CAS Registry Number.

Determination of the effect of cation-π interactions on the stability of α-oxy-organolithium compounds

Monje, Pablo,Paleo, M. Rita,Garcia-Rio, Luis,Sardina, F. Javier

supporting information; experimental part, p. 7394 - 7397 (2009/05/07)

(Chemical Equation Presented) Sn-Li exchange equilibria have allowed the quantification of the stabilizing effect of cation-π interactions in organolithium chemistry. Stabilization energy data on the effect of Li-π complexation of an aromatic ring or a C=C double bond in organolithium compounds are presented. The amount of stabilization gained by complexation of the Li atom with a π system in α-oxy-organolithium compounds is quite comparable to the one observed in systems containing Li-N or Li-O interactions.
