78028-03-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78028-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,2 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78028-03:
(7*7)+(6*8)+(5*0)+(4*2)+(3*8)+(2*0)+(1*3)=132
132 % 10 = 2
So 78028-03-2 is a valid CAS Registry Number.
