Check Digit Verification of cas no
The CAS Registry Mumber 687586-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,7,5,8 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 687586-53:
(8*6)+(7*8)+(6*7)+(5*5)+(4*8)+(3*6)+(2*5)+(1*3)=234
234 % 10 = 4
So 687586-53-4 is a valid CAS Registry Number.
