Check Digit Verification of cas no

The CAS Registry Mumber 1222190-45-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,1,9 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1222190-45:
(9*1)+(8*2)+(7*2)+(6*2)+(5*1)+(4*9)+(3*0)+(2*4)+(1*5)=105
105 % 10 = 5
So 1222190-45-5 is a valid CAS Registry Number.
