Check Digit Verification of cas no

The CAS Registry Mumber 650-90-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 650-90:
(5*6)+(4*5)+(3*0)+(2*9)+(1*0)=68
68 % 10 = 8
So 650-90-8 is a valid CAS Registry Number.
