Check Digit Verification of cas no
The CAS Registry Mumber 25357-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25357-81:
(7*2)+(6*5)+(5*3)+(4*5)+(3*7)+(2*8)+(1*1)=117
117 % 10 = 7
So 25357-81-7 is a valid CAS Registry Number.
