The CAS Registry Mumber 7012-31-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,1 and 2 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7012-31: (6*7)+(5*0)+(4*1)+(3*2)+(2*3)+(1*1)=59 59 % 10 = 9 So 7012-31-9 is a valid CAS Registry Number.
