20496-01-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20496-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,9 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20496-01:
(7*2)+(6*0)+(5*4)+(4*9)+(3*6)+(2*0)+(1*1)=89
89 % 10 = 9
So 20496-01-9 is a valid CAS Registry Number.
