Check Digit Verification of cas no

The CAS Registry Mumber 82203-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82203-19:
(7*8)+(6*2)+(5*2)+(4*0)+(3*3)+(2*1)+(1*9)=98
98 % 10 = 8
So 82203-19-8 is a valid CAS Registry Number.
