The CAS Registry Mumber 33885-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 33885-70: (7*3)+(6*3)+(5*8)+(4*8)+(3*5)+(2*7)+(1*0)=140 140 % 10 = 0 So 33885-70-0 is a valid CAS Registry Number.
