Check Digit Verification of cas no

The CAS Registry Mumber 221894-46-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,8,9 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221894-46:
(8*2)+(7*2)+(6*1)+(5*8)+(4*9)+(3*4)+(2*4)+(1*6)=138
138 % 10 = 8
So 221894-46-8 is a valid CAS Registry Number.
