Check Digit Verification of cas no

The CAS Registry Mumber 821785-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,1,7,8 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 821785-45:
(8*8)+(7*2)+(6*1)+(5*7)+(4*8)+(3*5)+(2*4)+(1*5)=179
179 % 10 = 9
So 821785-45-9 is a valid CAS Registry Number.
