Check Digit Verification of cas no

The CAS Registry Mumber 2019-05-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,1 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2019-05:
(6*2)+(5*0)+(4*1)+(3*9)+(2*0)+(1*5)=48
48 % 10 = 8
So 2019-05-8 is a valid CAS Registry Number.
