Check Digit Verification of cas no
The CAS Registry Mumber 25939-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,3 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25939-87:
(7*2)+(6*5)+(5*9)+(4*3)+(3*9)+(2*8)+(1*7)=151
151 % 10 = 1
So 25939-87-1 is a valid CAS Registry Number.
