The CAS Registry Mumber 7023-36-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,2 and 3 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 7023-36: (6*7)+(5*0)+(4*2)+(3*3)+(2*3)+(1*6)=71 71 % 10 = 1 So 7023-36-1 is a valid CAS Registry Number.
