Check Digit Verification of cas no

The CAS Registry Mumber 165274-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,2,7 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 165274-91:
(8*1)+(7*6)+(6*5)+(5*2)+(4*7)+(3*4)+(2*9)+(1*1)=149
149 % 10 = 9
So 165274-91-9 is a valid CAS Registry Number.
