The CAS Registry Mumber 20731-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,3 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20731-72:
(7*2)+(6*0)+(5*7)+(4*3)+(3*1)+(2*7)+(1*2)=80
80 % 10 = 0
So 20731-72-0 is a valid CAS Registry Number.
