Check Digit Verification of cas no

The CAS Registry Mumber 921209-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,2,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 921209-91:
(8*9)+(7*2)+(6*1)+(5*2)+(4*0)+(3*9)+(2*9)+(1*1)=148
148 % 10 = 8
So 921209-91-8 is a valid CAS Registry Number.
