258520-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258520-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,5,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 258520-85:
(8*2)+(7*5)+(6*8)+(5*5)+(4*2)+(3*0)+(2*8)+(1*5)=153
153 % 10 = 3
So 258520-85-3 is a valid CAS Registry Number.
