Check Digit Verification of cas no

The CAS Registry Mumber 189749-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189749-71:
(8*1)+(7*8)+(6*9)+(5*7)+(4*4)+(3*9)+(2*7)+(1*1)=211
211 % 10 = 1
So 189749-71-1 is a valid CAS Registry Number.
