139005-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139005-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,0 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139005-20:
(8*1)+(7*3)+(6*9)+(5*0)+(4*0)+(3*5)+(2*2)+(1*0)=102
102 % 10 = 2
So 139005-20-2 is a valid CAS Registry Number.
