Check Digit Verification of cas no

The CAS Registry Mumber 202148-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,1,4 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 202148-23:
(8*2)+(7*0)+(6*2)+(5*1)+(4*4)+(3*8)+(2*2)+(1*3)=80
80 % 10 = 0
So 202148-23-0 is a valid CAS Registry Number.
