The CAS Registry Mumber 20933-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,3 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20933-31:
(7*2)+(6*0)+(5*9)+(4*3)+(3*3)+(2*3)+(1*1)=87
87 % 10 = 7
So 20933-31-7 is a valid CAS Registry Number.
