Check Digit Verification of cas no

The CAS Registry Mumber 207789-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,7,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 207789-69:
(8*2)+(7*0)+(6*7)+(5*7)+(4*8)+(3*9)+(2*6)+(1*9)=173
173 % 10 = 3
So 207789-69-3 is a valid CAS Registry Number.
