Check Digit Verification of cas no
The CAS Registry Mumber 133589-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,8 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133589-03:
(8*1)+(7*3)+(6*3)+(5*5)+(4*8)+(3*9)+(2*0)+(1*3)=134
134 % 10 = 4
So 133589-03-4 is a valid CAS Registry Number.
