Check Digit Verification of cas no
The CAS Registry Mumber 467-32-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 467-32:
(5*4)+(4*6)+(3*7)+(2*3)+(1*2)=73
73 % 10 = 3
So 467-32-3 is a valid CAS Registry Number.
