Check Digit Verification of cas no

The CAS Registry Mumber 22019-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22019-71:
(7*2)+(6*2)+(5*0)+(4*1)+(3*9)+(2*7)+(1*1)=72
72 % 10 = 2
So 22019-71-2 is a valid CAS Registry Number.
