Check Digit Verification of cas no
The CAS Registry Mumber 13132-73-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,3 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13132-73:
(7*1)+(6*3)+(5*1)+(4*3)+(3*2)+(2*7)+(1*3)=65
65 % 10 = 5
So 13132-73-5 is a valid CAS Registry Number.
