Check Digit Verification of cas no

The CAS Registry Mumber 656820-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,8,2 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 656820-44:
(8*6)+(7*5)+(6*6)+(5*8)+(4*2)+(3*0)+(2*4)+(1*4)=179
179 % 10 = 9
So 656820-44-9 is a valid CAS Registry Number.
