67314-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67314-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,1 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67314-42:
(7*6)+(6*7)+(5*3)+(4*1)+(3*4)+(2*4)+(1*2)=125
125 % 10 = 5
So 67314-42-5 is a valid CAS Registry Number.
