The CAS Registry Mumber 91189-25-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,8 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91189-25:
(7*9)+(6*1)+(5*1)+(4*8)+(3*9)+(2*2)+(1*5)=142
142 % 10 = 2
So 91189-25-2 is a valid CAS Registry Number.
