The CAS Registry Mumber 75305-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,0 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 75305-96:
(7*7)+(6*5)+(5*3)+(4*0)+(3*5)+(2*9)+(1*6)=133
133 % 10 = 3
So 75305-96-3 is a valid CAS Registry Number.
