Check Digit Verification of cas no
The CAS Registry Mumber 25456-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,5 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25456-85:
(7*2)+(6*5)+(5*4)+(4*5)+(3*6)+(2*8)+(1*5)=123
123 % 10 = 3
So 25456-85-3 is a valid CAS Registry Number.
