Check Digit Verification of cas no

The CAS Registry Mumber 52988-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,8 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52988-15:
(7*5)+(6*2)+(5*9)+(4*8)+(3*8)+(2*1)+(1*5)=155
155 % 10 = 5
So 52988-15-5 is a valid CAS Registry Number.

, p. 901 - 912 (2007/10/02)

"Photochemical synthesis of polycyclic aromatic hydrocarbons and NMR-1H study of bay protons.Specific solvent effects and nuclear Overhauser effects".Dinaphthoanthracene (4a),9-bromo-dinaphthoanthracene (4b), 9-methyldinaphthoanthracene (4c), benzonaphthochrysene (7), benzonaphthoanthracene (3), naphthochrysene (9) and dibenzonaphthochrysene (12) have been synthesized by the photocyclodehydrogenation of 1,2-diarylethylenes (5,8) and bis (arylvinyl)arenes (6,10).The NMR study has been mainly focused on the bay protons involved in specific solvent effects Table 4) and nuclear Overhauser effects (Table 5).
