Check Digit Verification of cas no

The CAS Registry Mumber 71221-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,2 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71221-19:
(7*7)+(6*1)+(5*2)+(4*2)+(3*1)+(2*1)+(1*9)=87
87 % 10 = 7
So 71221-19-7 is a valid CAS Registry Number.
