Check Digit Verification of cas no
The CAS Registry Mumber 93898-53-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93898-53:
(7*9)+(6*3)+(5*8)+(4*9)+(3*8)+(2*5)+(1*3)=194
194 % 10 = 4
So 93898-53-4 is a valid CAS Registry Number.
