291-92-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 291-92-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 291-92:
(5*2)+(4*9)+(3*1)+(2*9)+(1*2)=69
69 % 10 = 9
So 291-92-9 is a valid CAS Registry Number.
