Check Digit Verification of cas no

The CAS Registry Mumber 20548-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,4 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20548-54:
(7*2)+(6*0)+(5*5)+(4*4)+(3*8)+(2*5)+(1*4)=93
93 % 10 = 3
So 20548-54-3 is a valid CAS Registry Number.
InChI:InChI=1/Ca.S/rCaS/c1-2
