Check Digit Verification of cas no

The CAS Registry Mumber 694489-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,4,4,8 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 694489-63:
(8*6)+(7*9)+(6*4)+(5*4)+(4*8)+(3*9)+(2*6)+(1*3)=229
229 % 10 = 9
So 694489-63-9 is a valid CAS Registry Number.
