Check Digit Verification of cas no
The CAS Registry Mumber 57497-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,9 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57497-39:
(7*5)+(6*7)+(5*4)+(4*9)+(3*7)+(2*3)+(1*9)=169
169 % 10 = 9
So 57497-39-9 is a valid CAS Registry Number.
