Check Digit Verification of cas no

The CAS Registry Mumber 188183-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,8 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188183-29:
(8*1)+(7*8)+(6*8)+(5*1)+(4*8)+(3*3)+(2*2)+(1*9)=171
171 % 10 = 1
So 188183-29-1 is a valid CAS Registry Number.
