Check Digit Verification of cas no
The CAS Registry Mumber 25016-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,1 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25016-11:
(7*2)+(6*5)+(5*0)+(4*1)+(3*6)+(2*1)+(1*1)=69
69 % 10 = 9
So 25016-11-9 is a valid CAS Registry Number.
