1157-45-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1157-45-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1157-45:
(6*1)+(5*1)+(4*5)+(3*7)+(2*4)+(1*5)=65
65 % 10 = 5
So 1157-45-5 is a valid CAS Registry Number.
