Check Digit Verification of cas no

The CAS Registry Mumber 142590-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,9 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142590-26:
(8*1)+(7*4)+(6*2)+(5*5)+(4*9)+(3*0)+(2*2)+(1*6)=119
119 % 10 = 9
So 142590-26-9 is a valid CAS Registry Number.

Novel uracil derivatives: Newly synthesized centrally acting agents

Imaizumi,Kano,Sakata

, p. 1808 - 1813 (2007/10/02)

A series of 1-amino-5-substituted uracils and their 4-thio or 2,4-dithio substituted analogues were synthesized and assayed for anti-conflict activity in rats and anesthetic activity in mice. 1-Amino-5-halogenouracils 3b-e, 1-amino-4-thiouracil (9a), and 1-amino-5-halogeno-4-thiouracils 9c, d showed both anti-conflict and anesthetic activities. The most active compound was 1-amino-5-chloro-4-thiouracil (9d) which showed anxiolytic activity at 2 mg/kg of oral administration (p.o.) on a modified Geller-Seifter conflict schedule. Its minimum effective dose (MED) was lower than that of diazepam. The 50 percent effective dose (ED50) for anesthetic activity in mice of the compound (9d) was 32.9 mg/kg, p.o.
