Check Digit Verification of cas no

The CAS Registry Mumber 103404-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,0 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103404-05:
(8*1)+(7*0)+(6*3)+(5*4)+(4*0)+(3*4)+(2*0)+(1*5)=63
63 % 10 = 3
So 103404-05-3 is a valid CAS Registry Number.

The Chemistry of Ethyl 2-Ethoxycarbonyl-5,5-diphenylpenta-2,3,4-trienoate, a Potential Precursor of Ph2C=C=C=C=C=O

Browne, Neil R.,Brown, Roger F. C.,Eastwood, Frank W.,Fallon, Gary D.

, p. 1675 - 1686 (2007/10/02)

The title diester, Ph2C=C=C=C(COOEt)2 (2), has been prepared by a Wittig reaction between (2-bromo-3,3-diphenylprop-2-en-1-yl)triphenylphosphonium bromide and diethyl 2-oxopropane-1,3-dioate (mesoxalic ester).The diester (2) undergoes cyclization reaction
