Check Digit Verification of cas no
The CAS Registry Mumber 133533-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,3 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133533-65:
(8*1)+(7*3)+(6*3)+(5*5)+(4*3)+(3*3)+(2*6)+(1*5)=110
110 % 10 = 0
So 133533-65-0 is a valid CAS Registry Number.
