Check Digit Verification of cas no

The CAS Registry Mumber 188530-36-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,3 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188530-36:
(8*1)+(7*8)+(6*8)+(5*5)+(4*3)+(3*0)+(2*3)+(1*6)=161
161 % 10 = 1
So 188530-36-1 is a valid CAS Registry Number.
