The CAS Registry Mumber 25490-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25490-40:
(7*2)+(6*5)+(5*4)+(4*9)+(3*0)+(2*4)+(1*0)=108
108 % 10 = 8
So 25490-40-8 is a valid CAS Registry Number.
