Check Digit Verification of cas no

The CAS Registry Mumber 1609692-69-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,6,9 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1609692-69:
(9*1)+(8*6)+(7*0)+(6*9)+(5*6)+(4*9)+(3*2)+(2*6)+(1*9)=204
204 % 10 = 4
So 1609692-69-4 is a valid CAS Registry Number.
