Check Digit Verification of cas no
The CAS Registry Mumber 4721-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4721-45:
(6*4)+(5*7)+(4*2)+(3*1)+(2*4)+(1*5)=83
83 % 10 = 3
So 4721-45-3 is a valid CAS Registry Number.
