139404-87-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139404-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,0 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139404-87:
(8*1)+(7*3)+(6*9)+(5*4)+(4*0)+(3*4)+(2*8)+(1*7)=138
138 % 10 = 8
So 139404-87-8 is a valid CAS Registry Number.
