1009-04-7

4-Pyrimidinecarboxamide, 1,2,3,6-tetrahydro-2,6-dioxo-N-methyl, also known as Barbital, is a barbiturate drug with the chemical formula C8H10N2O3. It is a white crystalline powder that is soluble in water and has sedative and hypnotic properties. Barbital was widely used as a sedative and anticonvulsant in the past, but its use has declined due to its potential for abuse, dependence, and severe withdrawal symptoms. It is still used in some veterinary applications and as a chemical intermediate in the synthesis of other barbiturates.

1009-04-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1009-04-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1009-04:
(6*1)+(5*0)+(4*0)+(3*9)+(2*0)+(1*4)=37
37 % 10 = 7
So 1009-04-7 is a valid CAS Registry Number.
