34833-73-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34833-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,3 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 34833-73:
(7*3)+(6*4)+(5*8)+(4*3)+(3*3)+(2*7)+(1*3)=123
123 % 10 = 3
So 34833-73-3 is a valid CAS Registry Number.
