Check Digit Verification of cas no

The CAS Registry Mumber 1219035-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,0,3 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1219035-41:
(9*1)+(8*2)+(7*1)+(6*9)+(5*0)+(4*3)+(3*5)+(2*4)+(1*1)=122
122 % 10 = 2
So 1219035-41-2 is a valid CAS Registry Number.
