The CAS Registry Mumber 6172-96-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,7 and 2 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6172-96: (6*6)+(5*1)+(4*7)+(3*2)+(2*9)+(1*6)=99 99 % 10 = 9 So 6172-96-9 is a valid CAS Registry Number.
