Check Digit Verification of cas no

The CAS Registry Mumber 198549-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,5,4 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 198549-12:
(8*1)+(7*9)+(6*8)+(5*5)+(4*4)+(3*9)+(2*1)+(1*2)=191
191 % 10 = 1
So 198549-12-1 is a valid CAS Registry Number.
