Check Digit Verification of cas no

The CAS Registry Mumber 5525-23-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5525-23:
(6*5)+(5*5)+(4*2)+(3*5)+(2*2)+(1*3)=85
85 % 10 = 5
So 5525-23-5 is a valid CAS Registry Number.

, p. 873 - 876 (1996)

New neutral radicals, 2-phenyl and 2-p-methoxyphenyl derivatives of 3-oxophenalenoxyl radical, were detected by ESR measurement. The radicals were generated by thermal decomposition of the dimers of the corresponding radicals and by oxidation of 2-phenyl-3-hydroxyphenalenone.
