The CAS Registry Mumber 2071-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,7 and 1 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2071-66: (6*2)+(5*0)+(4*7)+(3*1)+(2*6)+(1*6)=61 61 % 10 = 1 So 2071-66-1 is a valid CAS Registry Number.
