Check Digit Verification of cas no

The CAS Registry Mumber 884541-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,4,5,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 884541-19:
(8*8)+(7*8)+(6*4)+(5*5)+(4*4)+(3*1)+(2*1)+(1*9)=199
199 % 10 = 9
So 884541-19-9 is a valid CAS Registry Number.
