122911-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122911-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,1 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 122911-57:
(8*1)+(7*2)+(6*2)+(5*9)+(4*1)+(3*1)+(2*5)+(1*7)=103
103 % 10 = 3
So 122911-57-3 is a valid CAS Registry Number.
