The CAS Registry Mumber 29668-29-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,6 and 8 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 29668-29: (7*2)+(6*9)+(5*6)+(4*6)+(3*8)+(2*2)+(1*9)=159 159 % 10 = 9 So 29668-29-9 is a valid CAS Registry Number.
