Check Digit Verification of cas no

The CAS Registry Mumber 78904-82-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78904-82:
(7*7)+(6*8)+(5*9)+(4*0)+(3*4)+(2*8)+(1*2)=172
172 % 10 = 2
So 78904-82-2 is a valid CAS Registry Number.
