78840-83-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78840-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,4 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78840-83:
(7*7)+(6*8)+(5*8)+(4*4)+(3*0)+(2*8)+(1*3)=172
172 % 10 = 2
So 78840-83-2 is a valid CAS Registry Number.
