139007-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139007-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,0 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139007-97:
(8*1)+(7*3)+(6*9)+(5*0)+(4*0)+(3*7)+(2*9)+(1*7)=129
129 % 10 = 9
So 139007-97-9 is a valid CAS Registry Number.
