Check Digit Verification of cas no

The CAS Registry Mumber 1618664-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,6 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1618664-91:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*6)+(3*4)+(2*9)+(1*1)=197
197 % 10 = 7
So 1618664-91-7 is a valid CAS Registry Number.
