139484-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139484-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,8 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139484-12:
(8*1)+(7*3)+(6*9)+(5*4)+(4*8)+(3*4)+(2*1)+(1*2)=151
151 % 10 = 1
So 139484-12-1 is a valid CAS Registry Number.
