Check Digit Verification of cas no
The CAS Registry Mumber 139139-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139139-86:
(8*1)+(7*3)+(6*9)+(5*1)+(4*3)+(3*9)+(2*8)+(1*6)=149
149 % 10 = 9
So 139139-86-9 is a valid CAS Registry Number.
