The CAS Registry Mumber 39831-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39831-33:
(7*3)+(6*9)+(5*8)+(4*3)+(3*1)+(2*3)+(1*3)=139
139 % 10 = 9
So 39831-33-9 is a valid CAS Registry Number.
