The CAS Registry Mumber 1340481-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,4,8 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1340481-87:
(9*1)+(8*3)+(7*4)+(6*0)+(5*4)+(4*8)+(3*1)+(2*8)+(1*7)=139
139 % 10 = 9
So 1340481-87-9 is a valid CAS Registry Number.
