The CAS Registry Mumber 133941-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,4 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133941-32:
(8*1)+(7*3)+(6*3)+(5*9)+(4*4)+(3*1)+(2*3)+(1*2)=119
