Check Digit Verification of cas no
The CAS Registry Mumber 969-33-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,6 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 969-33:
(5*9)+(4*6)+(3*9)+(2*3)+(1*3)=105
105 % 10 = 5
So 969-33-5 is a valid CAS Registry Number.
