Check Digit Verification of cas no
The CAS Registry Mumber 20824-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,2 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20824-80:
(7*2)+(6*0)+(5*8)+(4*2)+(3*4)+(2*8)+(1*0)=90
90 % 10 = 0
So 20824-80-0 is a valid CAS Registry Number.
