139070-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139070-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139070-19:
(8*1)+(7*3)+(6*9)+(5*0)+(4*7)+(3*0)+(2*1)+(1*9)=122
122 % 10 = 2
So 139070-19-2 is a valid CAS Registry Number.
