Check Digit Verification of cas no
The CAS Registry Mumber 10111-25-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,1 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10111-25:
(7*1)+(6*0)+(5*1)+(4*1)+(3*1)+(2*2)+(1*5)=28
28 % 10 = 8
