139225-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139225-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,2 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139225-57:
(8*1)+(7*3)+(6*9)+(5*2)+(4*2)+(3*5)+(2*5)+(1*7)=133
133 % 10 = 3
So 139225-57-3 is a valid CAS Registry Number.
