Check Digit Verification of cas no

The CAS Registry Mumber 183551-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,5,5 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 183551-09:
(8*1)+(7*8)+(6*3)+(5*5)+(4*5)+(3*1)+(2*0)+(1*9)=139
139 % 10 = 9
So 183551-09-9 is a valid CAS Registry Number.
