Check Digit Verification of cas no

The CAS Registry Mumber 1291056-34-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,5 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1291056-34:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*5)+(3*6)+(2*3)+(1*4)=142
142 % 10 = 2
So 1291056-34-2 is a valid CAS Registry Number.
