91-28-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91-28-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91-28:
(4*9)+(3*1)+(2*2)+(1*8)=51
51 % 10 = 1
So 91-28-1 is a valid CAS Registry Number.
