Check Digit Verification of cas no

The CAS Registry Mumber 21203-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21203-48:
(7*2)+(6*1)+(5*2)+(4*0)+(3*3)+(2*4)+(1*8)=55
55 % 10 = 5
So 21203-48-5 is a valid CAS Registry Number.
