Check Digit Verification of cas no

The CAS Registry Mumber 928655-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,6,5 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 928655-45:
(8*9)+(7*2)+(6*8)+(5*6)+(4*5)+(3*5)+(2*4)+(1*5)=212
212 % 10 = 2
So 928655-45-2 is a valid CAS Registry Number.
