Check Digit Verification of cas no

The CAS Registry Mumber 1291091-40-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1291091-40:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*9)+(3*1)+(2*4)+(1*0)=141
141 % 10 = 1
So 1291091-40-1 is a valid CAS Registry Number.
