Check Digit Verification of cas no

The CAS Registry Mumber 131976-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,7 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131976-01:
(8*1)+(7*3)+(6*1)+(5*9)+(4*7)+(3*6)+(2*0)+(1*1)=127
127 % 10 = 7
So 131976-01-7 is a valid CAS Registry Number.

Anti-androgenic activity of substituted azo- and azoxy-benzene derivatives.

Takahashi,Ishioka,Koiso,Sodeoka,Hashimoto

, p. 1387 - 1390 (2007/10/03)

Substituted phenylazo and phenylazoxy compounds were systematically prepared and their anti-androgenic activity was measured in terms of (1) the growth-inhibiting effect on an androgen-dependent cell line, SC-3, and (2) the binding affinity to nuclear androgen receptor. Generally, azo/azoxy compounds showed cell toxicity, and the growth-inhibiting effects on SC-3 cells correlated with the toxicity. However, some compounds, including 4,4'-dinitroazobenzene (25), 4,4'-dimethoxyazobenzene (33), and 2,2'-dichloroazoxybenzene (47), possessed potent anti-androgenic activity without apparent cell toxicity.
