Check Digit Verification of cas no

The CAS Registry Mumber 290299-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,2,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 290299-89:
(8*2)+(7*9)+(6*0)+(5*2)+(4*9)+(3*9)+(2*8)+(1*9)=177
177 % 10 = 7
So 290299-89-7 is a valid CAS Registry Number.
