The CAS Registry Mumber 1271489-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,1,4,8 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1271489-34:
(9*1)+(8*2)+(7*7)+(6*1)+(5*4)+(4*8)+(3*9)+(2*3)+(1*4)=169
169 % 10 = 9
