Check Digit Verification of cas no

The CAS Registry Mumber 128219-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,1 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128219-50:
(8*1)+(7*2)+(6*8)+(5*2)+(4*1)+(3*9)+(2*5)+(1*0)=121
121 % 10 = 1
So 128219-50-1 is a valid CAS Registry Number.
