Check Digit Verification of cas no

The CAS Registry Mumber 869959-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,9,5 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 869959-35:
(8*8)+(7*6)+(6*9)+(5*9)+(4*5)+(3*9)+(2*3)+(1*5)=263
263 % 10 = 3
So 869959-35-3 is a valid CAS Registry Number.
