Check Digit Verification of cas no

The CAS Registry Mumber 219823-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,8,2 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219823-49:
(8*2)+(7*1)+(6*9)+(5*8)+(4*2)+(3*3)+(2*4)+(1*9)=151
151 % 10 = 1
So 219823-49-1 is a valid CAS Registry Number.
