Check Digit Verification of cas no

The CAS Registry Mumber 1620890-99-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,8,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1620890-99:
(9*1)+(8*6)+(7*2)+(6*0)+(5*8)+(4*9)+(3*0)+(2*9)+(1*9)=174
174 % 10 = 4
So 1620890-99-4 is a valid CAS Registry Number.
