Check Digit Verification of cas no

The CAS Registry Mumber 119198-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,9 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119198-90:
(8*1)+(7*1)+(6*9)+(5*1)+(4*9)+(3*8)+(2*9)+(1*0)=152
152 % 10 = 2
So 119198-90-2 is a valid CAS Registry Number.
