999-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 999-05-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 999-05:
(5*9)+(4*9)+(3*9)+(2*0)+(1*5)=113
113 % 10 = 3
So 999-05-3 is a valid CAS Registry Number.
