122091-57-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122091-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 122091-57:
(8*1)+(7*2)+(6*2)+(5*0)+(4*9)+(3*1)+(2*5)+(1*7)=90
90 % 10 = 0
So 122091-57-0 is a valid CAS Registry Number.
