Check Digit Verification of cas no
The CAS Registry Mumber 653-13-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 653-13:
(5*6)+(4*5)+(3*3)+(2*1)+(1*3)=64
64 % 10 = 4
So 653-13-4 is a valid CAS Registry Number.
