Check Digit Verification of cas no

The CAS Registry Mumber 57430-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,3 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57430-12:
(7*5)+(6*7)+(5*4)+(4*3)+(3*0)+(2*1)+(1*2)=113
113 % 10 = 3
So 57430-12-3 is a valid CAS Registry Number.

SYNTHESIS OF THREE NATURAL 1,3-DIARYLPROPANES: TWO REVISED STRUCTURES

Morais, Anselmo A.,Fo, Raimundo Braz,Fraiz, Silas V. Jr

, p. 239 - 242 (2007/10/02)

1-(2',4'-dihydroxy-3',5'-dimethylphenyl)-3-(2"-hydroxy-4",5"-methylenedioxyphenyl)-Propane, isolated from Iryanthera coriacea and I. laevis, 1-(2'-hydroxy-4'-methoxy-5'-methylphenyl)-3-(2"-hydroxy-4",5"-methylene-dioxyphenyl)-propane, isolated from I. laevis, and 1-(2'-hydroxy-4'-methoxyphenyl)-3-(3"-hydroxy-4"-methoxyphenyl)-propane, isolated from Virola multinervia, were synthesized by processes which involved catalityc hydrogenation of the appropriate chalcones and Clemmensen reduction of dihydrochalcones.Only the structures of 1,3-diarylpropanes isolated from V. multinervia and I. laevis were revised. - Keywords: Virola multinervia; Iryanthera coriaceae; I. laevis; Myristicaceae; 1,3-diarylpropanes; synthesis; reduction of chalcones and dihydrochalcones.
