Check Digit Verification of cas no

The CAS Registry Mumber 53681-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,8 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53681-13:
(7*5)+(6*3)+(5*6)+(4*8)+(3*1)+(2*1)+(1*3)=123
123 % 10 = 3
So 53681-13-3 is a valid CAS Registry Number.

Synthesis of pyrimidine derivatives possessing an antioxidative property and their inhibitory effects on picryl chloride-induced contact hypersensitivity reaction

Isobe, Yoshiaki,Hirota, Kosaku

, p. 1451 - 1454 (2007/10/03)

We conducted a preliminary structure-activity relationship (SAR) study of some barbituric acid and uracil derivatives against the picryl chloride-induced contact hypersensitivity reaction. The introduction of an antioxidative moiety to the side chain of the C(6)-position of uracil was effective against this model. The introduction of dimethoxyphenol (8b) or dimethylphenol (8c) instead of di-t-butylphenol (8a) as an antioxidative moiety gave diminished activities, so, the reactive oxygen would contribute to the inflammation of this model, and an antioxidative activity was required for exhibiting the inhibitory activity. The inhibitory activity was significantly affected by the substituent at the N(1)-phenyl moiety.
