3103-13-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3103-13-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,0 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3103-13:
(6*3)+(5*1)+(4*0)+(3*3)+(2*1)+(1*3)=37
37 % 10 = 7
So 3103-13-7 is a valid CAS Registry Number.
