The CAS Registry Mumber 18271-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,7 and 1 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 18271-61: (7*1)+(6*8)+(5*2)+(4*7)+(3*1)+(2*6)+(1*1)=109 109 % 10 = 9 So 18271-61-9 is a valid CAS Registry Number.
