Check Digit Verification of cas no

The CAS Registry Mumber 5045-23-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5045-23:
(6*5)+(5*0)+(4*4)+(3*5)+(2*2)+(1*3)=68
68 % 10 = 8
So 5045-23-8 is a valid CAS Registry Number.
