123371-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123371-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,7 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 123371-45:
(8*1)+(7*2)+(6*3)+(5*3)+(4*7)+(3*1)+(2*4)+(1*5)=99
99 % 10 = 9
So 123371-45-9 is a valid CAS Registry Number.
