Check Digit Verification of cas no

The CAS Registry Mumber 864427-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,4,2 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 864427-99:
(8*8)+(7*6)+(6*4)+(5*4)+(4*2)+(3*7)+(2*9)+(1*9)=206
206 % 10 = 6
So 864427-99-6 is a valid CAS Registry Number.
