5316-14-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5316-14-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,1 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5316-14:
(6*5)+(5*3)+(4*1)+(3*6)+(2*1)+(1*4)=73
73 % 10 = 3
So 5316-14-3 is a valid CAS Registry Number.
