Check Digit Verification of cas no

The CAS Registry Mumber 80253-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,5 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80253-16:
(7*8)+(6*0)+(5*2)+(4*5)+(3*3)+(2*1)+(1*6)=103
103 % 10 = 3
So 80253-16-3 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF BISDEHYDROANNULENEDIONES

Onishi, Yasunobu,Iyoda, Masahiko,Nakagawa, Masazumi

, p. 3641 - 3644 (2007/10/02)

Bisdehydro- and annulenediones have been synthesized by cyclic dimerization of corresponding ω-ethynyl acid chlorides in the presence of palladium-copper catalyst in triethylamine-benzene and fully characterized by analyses and their (1)H-NMR, mass, electronic and IR spectroscopic evidences.
