The CAS Registry Mumber 67216-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,1 and 6 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 67216-70: (7*6)+(6*7)+(5*2)+(4*1)+(3*6)+(2*7)+(1*0)=130 130 % 10 = 0 So 67216-70-0 is a valid CAS Registry Number.
