53050-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53050-28-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,0,5 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 53050-28:
(7*5)+(6*3)+(5*0)+(4*5)+(3*0)+(2*2)+(1*8)=85
85 % 10 = 5
So 53050-28-5 is a valid CAS Registry Number.

Kowalska, Alicja
, p. 2881 - 2890 (2008/12/23)
Substituted 7-methyl-2- or 6-purinethiones were obtained in series of reactions by nucleophilic substitution with oxygen, chloro, and sulfur nucleophiles. Oxidation of the sulfur atom at position 6 or 2 in purinethiones to corresponding disulfides depende
