The CAS Registry Mumber 133489-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,8 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133489-06:
(8*1)+(7*3)+(6*3)+(5*4)+(4*8)+(3*9)+(2*0)+(1*6)=132
132 % 10 = 2
So 133489-06-2 is a valid CAS Registry Number.
