The CAS Registry Mumber 39133-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,3 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39133-57:
(7*3)+(6*9)+(5*1)+(4*3)+(3*3)+(2*5)+(1*7)=118
118 % 10 = 8
So 39133-57-8 is a valid CAS Registry Number.
