34857-11-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34857-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,5 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34857-11:
(7*3)+(6*4)+(5*8)+(4*5)+(3*7)+(2*1)+(1*1)=129
129 % 10 = 9
So 34857-11-9 is a valid CAS Registry Number.
