Check Digit Verification of cas no

The CAS Registry Mumber 1818294-43-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,1,8,2,9 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1818294-43:
(9*1)+(8*8)+(7*1)+(6*8)+(5*2)+(4*9)+(3*4)+(2*4)+(1*3)=197
197 % 10 = 7
So 1818294-43-7 is a valid CAS Registry Number.
