Check Digit Verification of cas no

The CAS Registry Mumber 190441-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,4,4 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190441-44:
(8*1)+(7*9)+(6*0)+(5*4)+(4*4)+(3*1)+(2*4)+(1*4)=122
122 % 10 = 2
So 190441-44-2 is a valid CAS Registry Number.
