Check Digit Verification of cas no

The CAS Registry Mumber 180692-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,6,9 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180692-05:
(8*1)+(7*8)+(6*0)+(5*6)+(4*9)+(3*2)+(2*0)+(1*5)=141
141 % 10 = 1
So 180692-05-1 is a valid CAS Registry Number.
