Check Digit Verification of cas no

The CAS Registry Mumber 169896-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,8,9 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 169896-49:
(8*1)+(7*6)+(6*9)+(5*8)+(4*9)+(3*6)+(2*4)+(1*9)=215
215 % 10 = 5
So 169896-49-5 is a valid CAS Registry Number.
