The CAS Registry Mumber 1817-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 7 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1817-70: (6*1)+(5*8)+(4*1)+(3*7)+(2*7)+(1*0)=85 85 % 10 = 5 So 1817-70-5 is a valid CAS Registry Number.
