The CAS Registry Mumber 128191-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,9 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128191-31:
(8*1)+(7*2)+(6*8)+(5*1)+(4*9)+(3*1)+(2*3)+(1*1)=121
121 % 10 = 1
So 128191-31-1 is a valid CAS Registry Number.
