Check Digit Verification of cas no

The CAS Registry Mumber 20966-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,6 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20966-19:
(7*2)+(6*0)+(5*9)+(4*6)+(3*6)+(2*1)+(1*9)=112
112 % 10 = 2
So 20966-19-2 is a valid CAS Registry Number.
