Check Digit Verification of cas no
The CAS Registry Mumber 25269-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,6 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25269-16:
(7*2)+(6*5)+(5*2)+(4*6)+(3*9)+(2*1)+(1*6)=113
113 % 10 = 3
So 25269-16-3 is a valid CAS Registry Number.
