Check Digit Verification of cas no

The CAS Registry Mumber 188755-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,5 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188755-65:
(8*1)+(7*8)+(6*8)+(5*7)+(4*5)+(3*5)+(2*6)+(1*5)=199
199 % 10 = 9
So 188755-65-9 is a valid CAS Registry Number.
