The CAS Registry Mumber 1189557-99-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,5,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1189557-99:
(9*1)+(8*1)+(7*8)+(6*9)+(5*5)+(4*5)+(3*7)+(2*9)+(1*9)=220
220 % 10 = 0
So 1189557-99-0 is a valid CAS Registry Number.
