Check Digit Verification of cas no

The CAS Registry Mumber 497830-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,8,3 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 497830-90:
(8*4)+(7*9)+(6*7)+(5*8)+(4*3)+(3*0)+(2*9)+(1*0)=207
207 % 10 = 7
So 497830-90-7 is a valid CAS Registry Number.
