The CAS Registry Mumber 63271-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,7 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 63271-82:
(7*6)+(6*3)+(5*2)+(4*7)+(3*1)+(2*8)+(1*2)=119
119 % 10 = 9
