The CAS Registry Mumber 141280-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 141280-91:
(8*1)+(7*4)+(6*1)+(5*2)+(4*8)+(3*0)+(2*9)+(1*1)=103
103 % 10 = 3
