Check Digit Verification of cas no

The CAS Registry Mumber 53704-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,0 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 53704-25:
(7*5)+(6*3)+(5*7)+(4*0)+(3*4)+(2*2)+(1*5)=109
109 % 10 = 9
So 53704-25-9 is a valid CAS Registry Number.

EFFECT OF THE INCLUSION OF A CYCLIC FRAGMENT IN THE CHROMOPHORE ON THE PROPERTIES OF A SPIROPYRAN-MEROCYANINE SYSTEM

Gal'bershtam, M. A.,Sidorov, A. P.,Przhiyalgovskaya, N. M.,Strokach, Yu. P.,Barachevskii, V. A.,et. al.

, p. 923 - 928 (2007/10/02)

The corresponding merocyanines, which do not display a tendency to form spiropyran structures, are formed in the condensation of 1,3,3-trimethyl-2-methyleneindoline with 5-methyl-2-furoylacetaldehyde, 2-formylcyclohexanone, or 2-formyl-1-tetralone.Spiran compounds in which the spiropyran-merocyanine equilibrium is shifted markedly to favor the closed form are formed when 4a,9-dimethyl-2,3,4,4a-tetrahydrocarbazone - the cyclic analog of the Fischer base - is used in the reaction with salicylaldehydes and benzoylacetaldehydes.
