Check Digit Verification of cas no

The CAS Registry Mumber 221534-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,5,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 221534-34:
(8*2)+(7*2)+(6*1)+(5*5)+(4*3)+(3*4)+(2*3)+(1*4)=95
95 % 10 = 5
So 221534-34-5 is a valid CAS Registry Number.
