The CAS Registry Mumber 7071-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,7 and 1 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7071-02: (6*7)+(5*0)+(4*7)+(3*1)+(2*0)+(1*2)=75 75 % 10 = 5 So 7071-02-5 is a valid CAS Registry Number.
