Check Digit Verification of cas no
The CAS Registry Mumber 503157-04-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,1,5 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 503157-04:
(8*5)+(7*0)+(6*3)+(5*1)+(4*5)+(3*7)+(2*0)+(1*4)=108
108 % 10 = 8
So 503157-04-8 is a valid CAS Registry Number.

Fullerene ylidene malonate supramolecular triads
Garlaschelli, Luigi,Messina, Ivano,Pasini, Dario,Righetti, Pier Paolo
, p. 3385 - 3392 (2002)
This paper describes the synthesis and characterization of novel covalently bound fullerene ylidene malonate dyads in which the linker between the two units is a di-, tri-, or tetraethylene glycol unit. The synthesis involves a stepwise, convergent additi
