Check Digit Verification of cas no
The CAS Registry Mumber 4532-64-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,3 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4532-64:
(6*4)+(5*5)+(4*3)+(3*2)+(2*6)+(1*4)=83
83 % 10 = 3
So 4532-64-3 is a valid CAS Registry Number.
