The CAS Registry Mumber 716-70-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 6 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 716-70: (5*7)+(4*1)+(3*6)+(2*7)+(1*0)=71 71 % 10 = 1 So 716-70-1 is a valid CAS Registry Number.
