Check Digit Verification of cas no

The CAS Registry Mumber 248957-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,8,9,5 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 248957-72:
(8*2)+(7*4)+(6*8)+(5*9)+(4*5)+(3*7)+(2*7)+(1*2)=194
194 % 10 = 4
So 248957-72-4 is a valid CAS Registry Number.
