205238-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205238-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,2,3 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 205238-28:
(8*2)+(7*0)+(6*5)+(5*2)+(4*3)+(3*8)+(2*2)+(1*8)=104
104 % 10 = 4
So 205238-28-4 is a valid CAS Registry Number.
