Check Digit Verification of cas no

The CAS Registry Mumber 199740-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 199740-40:
(8*1)+(7*9)+(6*9)+(5*7)+(4*4)+(3*0)+(2*4)+(1*0)=184
184 % 10 = 4
So 199740-40-4 is a valid CAS Registry Number.
