The CAS Registry Mumber 96964-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,9,6 and 4 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 96964-72: (7*9)+(6*6)+(5*9)+(4*6)+(3*4)+(2*7)+(1*2)=196 196 % 10 = 6 So 96964-72-6 is a valid CAS Registry Number.
