Check Digit Verification of cas no

The CAS Registry Mumber 219323-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,3,2 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219323-50:
(8*2)+(7*1)+(6*9)+(5*3)+(4*2)+(3*3)+(2*5)+(1*0)=119
119 % 10 = 9
So 219323-50-9 is a valid CAS Registry Number.
