Check Digit Verification of cas no
The CAS Registry Mumber 13521-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13521-25:
(7*1)+(6*3)+(5*5)+(4*2)+(3*1)+(2*2)+(1*5)=70
70 % 10 = 0
So 13521-25-0 is a valid CAS Registry Number.
