Check Digit Verification of cas no

The CAS Registry Mumber 494748-27-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,7,4 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 494748-27:
(8*4)+(7*9)+(6*4)+(5*7)+(4*4)+(3*8)+(2*2)+(1*7)=205
205 % 10 = 5
So 494748-27-5 is a valid CAS Registry Number.
