Check Digit Verification of cas no

The CAS Registry Mumber 1291104-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,1,0 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1291104-19:
(9*1)+(8*2)+(7*9)+(6*1)+(5*1)+(4*0)+(3*4)+(2*1)+(1*9)=122
122 % 10 = 2
So 1291104-19-2 is a valid CAS Registry Number.
